Watercraft lift and automatic watercraft cover
A boat lift with hydraulically or mechanically actuated arms which self-installs a fitted three-dimensional boat cover on a powerboat. The control logic of the system allows for cover operation only when the lift is raised. A spring-tensioned roller keeps the cover tight and self-rolls the cover on the roller when the actuated arms are pivoted forward. The roller is hidden behind the boat in ‘cover-on’ position. A slip clutch prevents the torsion spring from being over tightened. The forward position of the roller is adjusted by adjusting the hydraulic cylinder length. The rearward position of the roller is adjusted by limiting the retracted position of the hydraulic cylinder. A non-hydraulic embodiment actuates the cover when the lift is operated.

Exhaust pipe for motorboat engine
InactiveCN101121440ASimple structureReduce noiseExhaust apparatusPropulsion power plantsExhaust pipeSeawater
The present invention discloses a vent pipe of an engine for a motorboat. An exhaust manifold (12) and an exhaust main (13) are double layer structure, that is, the exhaust manifold (12) consists of an external pipe of the manifold (2) and an internal pipe of the manifold (3) and the exhaust main (13) consists of an internal pipe of the exhaust main (5) and an external pipe of the exhaust main (6). The internal pipe of the manifold (3) and the internal pipe of the exhaust main (5) are connected to form a lining pipe body while the external pipe of the manifold (2) and the external pipe of the exhaust main (6) are connected to form an outer layer pipe body. A cavity is formed between the lining pipe body and the outer layer pipe body, that is, a channel for the cooling water. The technic proposal uses the flow of the seawater or the river water to cool the vent pipe, which can effectively reduce the temperature of the exhaust manifold and the exhaust main of the engine of the motorboat. The damp of the vapor can be discharged by a pore. The gas discharged by the vent pipe is silenced for the second time, which reduces the noise of the exhaust system and improves the amenity of the driving.

The invention relates to a cooling system of a motorboat engine, comprising a water pump assembly, a cooling water channel water chamber of the engine body cylinder body cover, an intake pipe joint and a thermostat seat, a general oil pan, an exhaust pipe and an auspuff flange and a sound attenuating system. The heat of the engine is transformed into the internal energy of cooling water and then discharged out of the motorboat; the cooling water pumped by the water pump assembly is divided into two ways which respectively cool the engine body, the general oil pan and an exhaust system comprising the exhaust pipe and the auspuff flange; the basic flow of the cooling water in the cylinder body cover is that the water flows from the bottom end part of the engine body to the top end part of the engine. By the adoption of the invention, the heat generated in the running process of the engine is transmitted to the cooling water instead of being emitted directly, and finally is discharged out of the motorboat by the cooling water, therefore, the cooling is reliable, the service performance and the safety performance of the motorboat are not affected by the gathering of a great deal of heat in the motorboat, thus conforming with the requirement of the motorboat engine to the cooling system.

Watercraft with steer-responsive throttle
InactiveUS20020127926A1Limit RPMAvoid overall overturningPropulsion power plantsEngine controllersSteering wheelSteering angle
A watercraft with a steer-responsive throttle generates thrust when the steerable propulsion unit is turned beyond a predetermined angular threshold. The turning of the steering wheel beyond the threshold causes the throttle to be opened so that the steerable propulsion unit produces a thrust at least equal to the minimal propulsive force needed to effectively steer the watercraft. A watercraft equipped with a steerresponsive throttle ensures that there is always sufficient thrust for steering the watercraft even when the operator fails to open the throttle manually. This steerresponsive throttle is applicable to single-engine personal watercraft, twin-engine jet boats or motorboats equipped with swivel-mounted outboard motors. In a first embodiment of the steer-responsive throttle, rotation of the steering wheel beyond the angular threshold causes an actuating cable to open the throttle. In a second embodiment, an electronic control system regulates the throttle by calculating the optimal throttle setting based on measurements derived from a speed sensor, a steering angle sensor and, optionally, a throttle position sensor.

Powerboat with disappearing tunnel
InactiveUS20050247252A1Reduce resistanceOvercome problemsPropulsive elementsFloating buildingsWater flowPropeller
A shallow draft boat has a hull that protects a propulsion propeller within a tunnel that passes only partially through the hull from stem to bow. The hull has a mechanism, such as a flap for selectively permitting or blocking water flow access to the tunnel from under the boat. The boat also has a lift mechanism for selectively positioning a propeller of a propulsion unit substantially directly behind the tunnel or below the tunnel. The boat can operate in two modes. In one, water access to the tunnel is permitted and the propeller is positioned above the bottom of the hull and behind the tunnel. In the other, water access to the tunnel is blocked and the propelles is positioned below the bottom of the hull. This construction permits selective operation in a shallow draft mode, in a normal draft mode or in between. In the shallow draft mode, the boat prevents propulsion unit malfunction by keeping obstacles, such as debris, crab pots and mammals such as manatees from contact with the propeller.
