[0001] This application is a divisional application of the application with the application number 202211631414.5 and the application date of 2022-12-19, and the title of "An Outboard Motor with Lateral and Aft Laydown Capability". TECHNICAL FIELD

[0002] The present disclosure relates to outboard motors, and in particular to manually transportable outboard motors with lateral and aft laydown capability. BACKGROUND

[0003] The following is incorporated by reference in its entirety.

[0004] U.S. Patent No. 9,205,906 discloses a mounting arrangement for supporting an outboard motor extending in a fore-aft plane relative to a marine vessel. The mounting arrangement includes first and second mounts, each having an outer shell, an inner wedge disposed concentrically in the outer shell, and a resilient spacer between the outer shell and the inner wedge. Each of the first and second mounts extends along an axial direction, along a vertical direction perpendicular to the axial direction, and along a horizontal direction perpendicular to the axial direction and to the vertical direction. The inner wedge of each of the first and second mounts has a non-circular shape when viewed in a cross-section perpendicular to the axial direction. The non-circular shape includes a first outer surface extending laterally at a first angle to the horizontal and vertical directions. The non-circular shape includes a second outer surface extending laterally at a second, different angle to the horizontal and vertical directions. A method is used to manufacture the mounting arrangement.

[0005] U.S. Patent No. 9,701,383 discloses a marine propulsion support system having a transom bracket, a swivel bracket, and a mounting bracket. A drive unit is connected to the mounting bracket by a plurality of vibration isolation mounts configured to absorb loads on the drive unit that do not exceed a mounting design threshold. A cushioning bumper between the swivel bracket and the drive unit limits deflection of the drive unit caused by loads that exceed the threshold. An outboard motor includes a transom bracket, a swivel bracket, a carriage, and a drive unit supported between opposing first and second arms of the carriage. First and second vibration isolation mounts connect the first and second carriage arms, respectively, to the drive unit. An upper motion-limiting bumper is located distally from the vibration isolation mounts and between the swivel bracket and the drive unit.

[0006] U.S. Patent No. 9,764,813 discloses a tiller for an outboard motor. The tiller includes a tiller body extending along a tiller axis between a fixed end and a free end. A throttle grip is disposed on the free end. The throttle grip is rotatable through a first (left hand) range of motion from an idle position in which the outboard motor is controlled at an idle speed to a first (left hand) wide open throttle position in which the outboard motor is controlled at a wide open throttle speed, and alternately through a second (right hand) range of motion from the idle position to a second (right hand) wide open throttle position in which the outboard motor is controlled at the wide open throttle speed.

[0007] U.S. Patent No. 11,097,824 discloses an apparatus for steering an outboard motor relative to a marine vessel. The apparatus includes a transom bracket configured to support the outboard motor relative to the marine vessel; a tiller for manually steering the outboard motor relative to a steering axis; a steering arm extending above the transom bracket and coupling the tiller to the outboard motor such that rotation of the tiller causes the outboard motor to rotate relative to the steering axis, wherein the steering arm is positioned above the transom bracket; and a secondary steering device configured to lock the outboard motor in each of a plurality of steering positions relative to the steering axis. The secondary steering device extends above the steering arm and is manually operable from above the steering arm.

[0008] U.S. Patent Application No. 17 / 487,116 discloses an outboard motor including a transom clamp bracket configured to be supported on a transom of a marine vessel and a swivel bracket configured to be supported by the transom clamp bracket. A propulsion unit is supported by the swivel bracket, the propulsion unit including a head unit, a middle portion below the head unit, and a lower unit below the middle portion. When the outboard motor is in a neutral tilt / horizontal position, the head unit, the middle portion, and the lower unit are generally vertically aligned with one another. The propulsion device is detachable from the transom clamp bracket. SUMMARY

[0009] This summary is intended to introduce a series of concepts that will be further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

[0010] In non-limiting examples of the present disclosure, the outboard motor extends in an axial direction from a top to a bottom, in a lateral direction perpendicular to the axial direction from one side to another, and in a longitudinal direction perpendicular to the axial direction and perpendicular to the lateral direction from a front to a back. The outboard motor has a cowl; a gear case; a middle portion axially between the cowl and the gear case; a steering arm extending forward from the middle portion; and a wing extending laterally from the steering arm, wherein the wing, sides of the cowl, and sides of the gear case together define a side tripod that supports the outboard motor in a side down position.

[0011] In other non-limiting examples of the disclosure, the tiller extends forward from the steering arm. The wing is located aft of the tiller and forward of the intermediate portion, and has support members on the sides of the cowling. The support members are configured to support the outboard motor in the laterally lowered position with the sides of the wing and the gear case. The wing includes a frame having an inner end coupled to the steering arm, and an outer end having a foot with a flat surface for supporting the outboard motor in the laterally lowered position with the sides of the cowling and the gear case.

[0012] In other non-limiting examples of the disclosure, the outboard motor has a windscreen between the intermediate portion and the gear case, the windscreen having a rear edge with laterally outer rear support members that form a rear tripod with the rear of the cowling, the rear tripod supporting the outboard motor in the rearward lowered position.

[0031] In the course of research and development in the field of marine propulsion devices, the present applicant determined that it would be advantageous to provide an improved locking device for removably coupling a marine drive, such as an outboard motor, to a marine vessel. Further, the present applicant determined that it would be advantageous to provide an improved coxswain device to selectively hold the marine drive in various steering directions. Further still, the present applicant determined that it would be advantageous to integrate the coxswain device with the locking device to provide a more efficient and effective means for collectively locking, unlocking, and holding the steering direction of the marine drive relative to the marine vessel, which advantageously reduces the likelihood of user error, limits the potential for accidental damage to the equipment, and enhances the overall user experience.

[0032] Figure 1A marine drive, in the illustrated example an outboard motor 10, is depicted. The outboard motor 10 has an upper cowling 12 and a driveshaft housing 14 extending downwardly from the upper cowling 12 to a lower gearcase 16. A powerhead 18 is covered by the upper cowling 12. The powerhead 18 causes rotation of a driveshaft 20 which extends from the powerhead 18 through the driveshaft housing 14 to engage a propeller shaft 22 which is supported for rotation in the lower gearcase 16. The powerhead 18 can include an electric motor and / or an engine and / or any other conventional means for rotating the driveshaft 20. Rotation of the driveshaft 20 causes rotation of the propeller shaft 22 which in turn causes rotation of a propeller 15. The type and configuration of the marine drive can be different than that illustrated, and in other examples can include a forward or tractor propeller configuration, a impeller, and / or any other known means for producing a propulsive force in water to propel a marine vessel.

[0033] Reference is made to Figure 1 and Figure 2 The outboard motor 10 is coupled to a transom 24 of a marine vessel 26 by a transom bracket assembly 30 which in the illustrated example includes a transom bracket 32 secured to the transom 24 and a swivel bracket 34 pivotably coupled to the transom bracket 32. The transom bracket 32 has a pair of C-shaped arms 36 which are mounted on top of the transom 24 and a pair of threaded plunger clamps 40 which clamp the C-shaped arms 36 to the transom 24. Rotation of a handle 43 in one direction clamps the transom 24 between the C-shaped arms 36 and the plunger clamps 40. Rotation of the handle 43 in the opposite direction releases the C-shaped arms 36 to be removed from the transom 24. The type and construction of the transom bracket 32 can be different than that illustrated and described. In other examples, the transom bracket 32 is secured to the transom 24 by fasteners.

[0034] The swivel bracket 34 is pivotably coupled along a horizontal axis 38 to upper ends of the C-shaped arms 36 so that the swivel bracket 34 is pivotable (adjustable) up and down about the horizontal axis 38 in the direction of arrow 39. Reference is made to the above-incorporated U.S. patents which show similar conventional arrangements to facilitate pivotal movement of the swivel bracket relative to the transom bracket. This is a conventional arrangement and therefore will not be discussed further herein. For the sake of completeness, it should also be mentioned that for the purposes of the present invention, the transom bracket assembly 30 is not necessarily required to have a swivel bracket which is pivotable (adjustable) relative to the transom bracket. In other arrangements, the transom bracket assembly can consist of a single unitary component or can consist of more than one component which is not pivotable about a horizontal axis.

[0035] Reference is now made to Figure 3The rotating bracket 34 includes a rotating arm 42 having a first end 44 pivotably coupled to the C-arm 36 of the square transom bracket 32 along the horizontal axis 38. The rotating arm 42 has an opposite second end 46 secured to or formed with an elongated rotating cylinder 48, described below with reference to Figure 5 Further description. As shown in Figure 3 and Figure 4 , the first end 44 of the rotating arm 42 has a pair of side walls 50 and a top wall 52 connecting the side walls 50. An axial passage 54 (see Figure 5 ) passes through a middle portion of the rotating arm 42 between the first end 44 and the second end 46, generally proximate to the top wall 52, proximate to and between the side walls 50.

[0036] With reference to Figure 1 to Figure 3 , the turning bracket 60 is secured to and extends from the outboard motor 10 generally along a middle portion of the outboard motor 10, proximate to a lower portion of the upper cowling 12 and an upper portion of the drive shaft housing 14. As will be further described below, the turning bracket 60 facilitates detachable coupling of the outboard motor 10 to the square transom bracket assembly 30, i.e., so that the outboard motor 10 is turnable relative to the square transom bracket assembly 30 about a turning axis 62, and so that the outboard motor 10 is removable from the square transom bracket assembly 30 for transport with the outboard motor 10. The turning bracket 60 has a turning arm 64 and a rotating tube assembly 66. The rotating tube assembly 66 is cylindrical, having a smooth outer surface extending generally laterally from an upper end 70 secured to a middle portion of the turning arm 64 by fasteners 72 to a conical lower end 75. The turning arm 64 has a first end 74 secured to the support frame or other component of the outboard motor 10, as described above, and an opposite second end 76 secured to a conventional tiller 78 by fasteners extending through holes 77 in end walls 79 of the turning arm 64, as shown in Figure 1 . The type and configuration of the tiller 78 can differ from that shown. The example shown is the tiller disclosed in currently incorporated U.S. Patent No. 9,764,813.

[0037] With reference to Figure 3 , the outboard motor 10 is mounted to the rotating bracket 34 by lowering the outboard motor 10 into the rotating cylinder 48 through the rotating tube assembly 66, as shown in Figure 3The rotating cylinder 48 has a widened mouth 80. A receiving cup 82 nests in the widened mouth 80 and is secured thereto by fasteners 84. An annular locking flange 86 is secured to the upper end 70 of the rotating tube assembly 66. The receiving cup 82 and the annular locking flange 86 have complementary interior and exterior shapes, respectively, such that when the rotating tube assembly 66 is lowered into the rotating cylinder 48 and installed within the rotating cylinder 48, the annular locking flange 86 nests in the receiving cup 82. The receiving cup 82 has an interior funneling surface 88 that funnels the conical lower end 75 of the rotating tube assembly 66 centrally into the rotating cylinder 48 as the rotating tube assembly 66 is lowered into the receiving cup 82. The smooth exterior surface of the rotating tube assembly 66 facilitates the sliding of the rotating tube assembly 66 along the smooth interior surface of the rotating cylinder 48 until the annular locking flange 86 engages and nests in the receiving cup 82. The engagement between the outer profile of the annular locking flange 86 and the interior (funneling) profile of the receiving cup automatically aligns the rotating tube assembly 66 about the steering axis 62, preferably into the position shown in Figure 5

[0038] Referring to Figure 5 , the rotating tube assembly 66 has a stationary outer cylinder 90 and a rotatable inner cylinder 92, the inner cylinder 92 being coaxially disposed within the outer cylinder 90. The upper end of the inner cylinder 92 is secured to the steering arm 64 by fasteners 72 such that manual manipulation of the tiller 78 about the steering axis 62, as will be further described below, rotates the steering arm 64 and the inner cylinder 92 about the steering axis 62 while the outer cylinder 90 and the annular locking flange 86 remain stationary relative to the steering axis 62 due to the nested engagement between the annular locking flange 86 and the receiving cup 82 as described. A bearing 94 facilitates the rotational (steering) movement of the inner cylinder 92 relative to the outer cylinder 90 of the rotating tube assembly 66.

[0039] Referring now to Figure 3 and Figure 4 , the novel integrated co-pilot and locking mechanism 100 is configured to hold the steering bracket 60 in a plurality of steering directions relative to the steering axis 62. The mechanism 100 is further configured to lock and alternately unlock the steering bracket 60 relative to the sponson bracket assembly 30 such that in the locked position of the mechanism 100, the outboard motor 10 is held on the sponson bracket assembly 30 and thus on the marine vessel 26, and such that in the unlocked position of the mechanism 100, the outboard motor 10 is able to be removed therefrom.

[0040] ​Generally, mechanism 100 has a co-pilot arm 102 (comprising multiple components in the illustrated embodiment) for holding the steering bracket 60 in a selected steering direction about the steering axis 62 and for releasing the steering bracket 60 to allow the outboard motor 10 to steer freely about the steering axis 62. Mechanism 100 also has a locking arm 104 for locking and alternatively unlocking the steering bracket 60 and thus the outboard motor 10 relative to the stern bracket assembly 30 and therefore relative to the marine vessel 26. As shown and described below, the co-pilot arm 102 and the locking arm 104 are parallel and coaxial, with the co-pilot arm 102 integrated within and supported on the locking arm 104 and movable relative to it.

[0041] refer to Figure 3 to Figure 4 The locking arm 104 extends generally laterally relative to the steering axis 62 and extends perpendicularly to the steering axis 62 along the steering arm 64. The locking arm 104 has a first handle end 106, an opposing second locking end 108, and an intermediate portion 109 between the handle end 106 and the locking end 108. The intermediate portion 109 of the locking arm 104 extends along the swivel arm 42 and through the axial channel 54. A bracket 110 connects the locking arm 104 to the bottom of the handle end 106 of the steering arm 64, allowing the locking arm 104 to slide radially toward and away from the swivel tube assembly 66 along the steering arm 64. The bracket 110 has opposing cross arms 112 and opposing bracket arms 113 for supporting the locking arm 104, the bracket arms being fixed to the end wall 114 along the bottom of the steering arm 64 adjacent to the axial channel 54.

[0042] An end flange 116 is provided on the handle end 106. (See below for reference.) Figure 5 to Figure 8 In further detail, the end flange 116 provides a locking handle that facilitates manual gripping of the locking arm 104 and pulling / sliding it radially outward from the rotary tube assembly 66 to engage the locking end 108 from the top flange 118 of the annular locking flange 86 (see...). Figure 3 and Figure 7 Remove from above, thereby releasing or unlocking the outboard motor 10 for removal from the stern bracket assembly 30. The end flange 116 also facilitates the locking arm 104 to be pushed / slid radially inward toward the rotary tube assembly 66 to move the locking end 108 above the top flange 118 (e.g., Figure 5 and Figure 6 As shown), the rotary tube assembly 66 is locked onto the stern bracket assembly 30, thereby preventing the outboard motor 10 from being removed from the stern bracket assembly 30.

[0043] The stop device 120 holds the locking arm 104 in the locked position (e.g.) Figure 5 to Figure 6 (as shown and described below) and unlock location (as follows)Figure 7 The type and configuration of the stop device can differ from that shown and described below. In the example shown, the stop device 120 has a stop tab 121 extending from the bottom of the locking end 108 of the locking arm 104 and a spring clip 122 extending radially from the upper flange on the receiving cup 82. The spring clip 122 has a pair of spring arms 124 with a wave profile defined by an open outer end therebetween for receiving the stop tab 121, a first (outer) recess for retaining the stop tab 121 when the locking arm 104 is in the unlocked position, and a second (inner) recess for retaining the stop tab 121 when the locking arm 104 is in the locked position, located closer to the receiving cup 82.

[0044] Reference is made to Figure 3 The co-driver arm 102 has a friction arm 130, a shuttle 132, and a handle or crank 134. The friction arm 130 and the shuttle 132 extend generally parallel to and coaxially with the locking arm 104. The friction arm 130 is disposed in an elongated channel formed by the locking end 108 of the locking arm 104 and is slidable along the locking arm 104. A spring 138 has a first end abutting an abutment wall 136 on the bottom of the friction arm 130 and an opposite second end disposed on a spring retention finger 140 at the bottom of the locking end 108 of the locking arm 104. As shown, the natural spring force of the spring 138 pushes the abutment wall 136 and the spring retention finger 140 apart, thereby biasing the friction arm 130 toward and into engagement with the shuttle 132. Figure 4

[0045] ​The shuttle 132 is nested into the top of the locking arm 104, having an elongated shuttle body 142, an abutment flange 144 extending downwardly from the shuttle body 142, through a groove 145 in the intermediate portion 109 of the locking arm 104, and into engagement with an outer end flange 146 on the friction arm 130, and a threaded sleeve 148 extending downwardly from the shuttle body 142 through a groove 150 in the handle end 106 of the locking arm 104. The threaded sleeve 148 is in engagement with a threaded shaft 151 on the knob 134, which extends through an unthreaded hole 154 in the end flange 116. A spring 156 has a first end abutting the threaded sleeve 148, and an opposite second end abutting a rear side of the end flange 116, opposite the knob 134. The natural spring force of the spring 156 tends to urge the shuttle 132 away from the rear side of the end flange 116. Manually rotating the knob 134 in a first direction causes the threaded sleeve 148 of the shuttle 132 to move inwardly toward the rotating tube assembly 66, causing the shuttle 132 to move inwardly (shuttle) along the locking arm 104. Moving the shuttle 132 inwardly pushes the friction arm 130 inwardly toward the rotating tube assembly 66 until an inner end 160 of the friction arm 130 engages an annular friction ring 162 on the inner tube 92 of the rotating tube assembly 66. Optionally, the inner end 160 of the friction arm 130 has a concave surface that generally conforms to an outer surface of the annular friction ring 162, thereby facilitating frictional engagement therebetween. The frictional engagement between the inner end 160 and the annular friction ring 162 frictionally retains the inner tube 92 and associated steering arm 64, and thus the steering orientation of the outboard motor 10 rigidly attached to the steering arm 64.

[0046] Conversely, manually rotating the knob 134 in an opposite second direction causes the threaded sleeve 148 and associated shuttle 132 to move outwardly (shuttle) along the locking arm 104, away from the rotating tube assembly 66. Moving the shuttle 132 outwardly allows the natural bias of the spring 138 to move the friction arm 130 away from the annular friction ring 162, thereby eliminating the frictional engagement between the inner end 160 and the annular friction ring 162, which in turn releases the rotating tube assembly 66 and associated outboard motor 10 for steering movement about the steering axis 62, as described above.

[0047] Advantageously, the coxswain arm 102 is configured such that by the degree of rotation of the knob 134, the friction arm 130 is selectively movable either inwardly toward the annular friction ring 162 or alternatively outwardly away from the annular friction ring 162, thereby allowing the user to vary the strength of the frictional engagement between the coxswain arm 102 and the rotating tube assembly 66, and thus, provide the ability to selectively vary the amount of resistance to the steering motion of the outboard motor 10 relative to the transom bracket assembly 30. Thus, the mechanism 100 allows the user to control the degree of resistance to the steering motion of the outboard motor 10 by the tiller 78, i.e., according to personal preference. As a personal choice, some users prefer more resistance to the steering input than others. The mechanism 100 advantageously allows the user to selectively vary and set this characteristic.

[0048] Figure 5 The mechanism 100 is shown in the locked position with the steering bracket 60 held on the transom bracket assembly 30. The coxswain arm 102 is shown disengaged from the rotating tube assembly 66, such that the steering bracket 60 and associated outboard motor 10 are free to steer about the steering axis 62 by the tiller 78. As noted above, during installation, the rotating tube assembly 66 is lowered into the rotating bracket 34 such that the annular locking flange 86 is nested into the receiving cup 82. The end flange 116 is then manually pushed inwardly toward the rotating tube assembly 66 to move the locking end 108 above the top of the top flange 118, thereby locking the rotating tube assembly 66 on the transom bracket assembly 30. In other words, the locking end 108 prevents the annular locking flange 86 from moving upwardly, thereby preventing the rotating tube assembly 66 from being removed from the rotating cylinder 48. The movement of the locking end 108 above the top of the top flange 118 also moves the detent projection 121 from the outer recess of the spring clip 122 to the inner recess, which holds the locking arm 104 in the illustrated position. The knob 134 is shown rotated to a position in which the shuttle 132 is moved outwardly away from the rotating tube assembly 66, thereby allowing the natural bias of the spring 138 to move the friction arm 130 away from the annular friction ring 162, as shown, thereby preventing the frictional engagement between the inner end 160 and the annular friction ring 162, which releases the rotating tube assembly 66 and associated outboard motor 10 for steering motion.

[0049] Figure 6 The mechanism 100 is shown in the locked position after the coxswain handle 134 has been manually rotated as shown by the arrow 200, such that the shuttle 132 is moved inwardly toward the rotating tube assembly 66, which in turn moves the friction arm 130 toward the annular friction ring 162, as shown by the arrow 201, and into frictional engagement therewith, which frictional engagement opposes or resists the steering motion of the rotating tube assembly 66 and associated tiller 78 and outboard motor 10 relative to the transom bracket assembly 30. Thus, Figure 6The mechanism 100 is depicted in the locked position, wherein the co-pilot arm 102 restricts the steering movement of the outboard motor 10 about the steering axis 62.

[0050] Figure 7 The mechanism 100 is shown in the unlocked position after the end flange 116 is pulled / slid radially outward away from the rotary tube assembly 66, as indicated by arrow 202, thereby removing the locking end 108 from above the top flange 118 of the annular locking flange 86. This releases or unlocks the outboard motor 10 for removal from the stern bracket assembly 30, as indicated by arrow 204. Advantageously, the co-pilot arm 102 is held in position relative to the locking arm 104, i.e., regardless of whether the locking arm 104 is in the locked or unlocked position. That is, as the locking arm 104 moves into and out of the locked and unlocked positions and moves between the locked and unlocked positions, the frictional engagement setting of the co-pilot arm 102 remains constant, thereby allowing the operator of the mechanism 100 to lock and unlock the device without losing its preferred frictional engagement (i.e., its preferred steering resistance setting).

[0051] Therefore, it can be seen that this disclosure provides a novel integrated co-pilot and locking mechanism, including a co-pilot arm for holding a steering bracket on a marine drive in each of a plurality of steering directions, and a locking arm configured to lock and alternately unlock the steering bracket relative to the stern bracket assembly, specifically such that in the locked position, the marine drive is held on the stern bracket assembly, and that in the unlocked position, the marine drive can be removed from the stern bracket assembly. This novel mechanism includes a single, multi-functional handle end (106, 116, 134) which is effectively operable to hold the steering bracket in each of the plurality of steering directions, and is also operable to lock and alternately unlock the steering bracket and stern bracket assembly relative to each other.

[0052] During the research and development process, the inventors realized that it was desirable to construct marine drives, such as outboard motors, that could be easily lifted from a position on a marine vessel, or from a sideways or rear-down position, transported to another location, and then safely returned to the ground or other supporting surface without damaging the fairing and other fragile components of the marine drive. This disclosure is the result of the inventors' efforts in this regard.

[0053] Figure 8 to Figure 11An embodiment of the outboard motor 10 is shown.

[0060] like Figure 13 As shown, the outboard motor 10 is positioned laterally downwards on the support surface 320. As illustrated, the outboard motor 10 is fully supported on the support surface 320 by a side tripod formed by the outer plane surface 216 of the wing 210's base 214, the first support member 286 on the side fairing side 276 of the fairing 12 facing the support surface 320, and the side of the lower gearbox 16 facing the support surface 320, particularly along the outer diameter of its main body portion 302. It should be understood that... Figure 13 The outboard motor 10 is depicted in one of two opposing side-down positions, with only one wing 210 configured in one side-down position to form a side tripod together with the side of the first support member 286 and the lower gearbox. In the illustrated position, the opposing wings 210 along the ribbed gripping surface 221 provide a convenient location for manually gripping and moving the outboard motor 10. Alternatively, the rudder 78 and / or the rotary tube assembly 66 provide convenient locations for gripping and raising the outboard motor.

[0061] Figure 14The outboard motor 10 is shown in a rear-down position on support surface 320. As shown, the outboard motor 10 is fully supported on support surface 320 by a rear tripod consisting of the flat rear surface 296 of the second support member 292 on the rear apex portion 272 of the fairing 12 and the rear support member 318 on the tail portion 312 of the wind deflector 304. In this direction, the rudder 78 and / or the rotary tube assembly 66 provide convenient positions for gripping and lifting the outboard motor 10. Alternatively, either or both wings 210 can be manually gripped to lift the outboard motor 10.

[0062] Therefore, those skilled in the art will understand that this disclosure provides an improved outboard motor configuration that can be easily and safely lifted, transported, and then placed on the ground or other supporting surface in a manner that reduces the possibility of damage to the outboard motor during the process. In use, the rudder can be manually turned to... Figure 13 and Figure 14 The storage location is shown.
