Benefits of technology

[0008]Therefore, preferred embodiments of the present invention provide a boat propelling apparatus which can be manufactured at a reduced cost.

Problems solved by technology

However, according to the technique in JP-A 2005-193810, there is a problem of increased number of parts and increased cost of manufacture since the technique requires a clamp bracket and an outboard-engine mounting unit in addition to a mounting member and a swivel bracket in order to mount the outboard engine (boat propelling apparatus) onto a side portion of the boat body.
Especially, the supporting block, which has a C-shaped cross-section made by machining a metal ingot into the shape, which takes time to manufacture, is not suitable for mass production and therefore results in increased cost of manufacture.

Embodiment Construction

[0045]Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0046]Referring to FIG. 1 and FIG. 2, an outboard engine 10 according to a preferred embodiment of the present invention is an example of the boat propelling apparatus.

[0047]FIG. 3 shows a so-called double-ender boat S1 in which both of the front and the rear end portions have a pointed shape in a plan view. FIG. 4 shows a boat body S2 of a so-called traditional Japanese type in which the rear end portion extends substantially perpendicularly in a plan view, to a travelling direction indicated by Arrow FWD. The outboard engine 10 is mountable to whichever of boat edges E1, E2 in side portions of the double-ender boat S1 and a boat edge E3 in a rear portion of the traditional Japanese-style boat body S2.

[0048]First, description will cover a case where the outboard engine 10 is mounted to the boat edge E1 in the right side portion of the double-ender boat S1.

Abstract

A boat propelling apparatus includes an outboard engine including an outboard engine main body arranged to propel a boat; a trim bracket which includes mutually opposed platy side portions and a platy front portion connecting the side portions with each other, and arranged to pivotably support the outboard engine main body; and a clamp bracket which is mountable to and demountable to a boat edge and is connected with the trim bracket via one of the side portions and the front portion. The clamp bracket includes a swivel bracket mounted to the trim bracket and a holding portion which holds the swivel bracket. The swivel bracket has a convex portion whereas the holding portion has a concave portion. The concave portion and the convex portion have an identical curvature.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to boat propelling apparatuses, and more specifically to a boat propelling apparatus which includes a bracket for mounting to an edge of a boat.[0003]2. Description of the Related Art[0004]A conventional technique of this kind is disclosed in JP-A 2005-193810, for example. JP-A 2005-193810 discloses an outboard-engine mounting system which includes a mounting member for mounting to an edge of a boat; an outboard-engine mounting unit fixed to the mounting member; and a clamp bracket and a swivel bracket for connecting the outboard-engine mounting unit and the outboard engine main body with each other. The outboard-engine mounting unit included in the outboard-engine mounting system according to JP-A 2005-193810 allows an outboard engine (boat propelling apparatus) to be mounted on a side portion of a boat body.[0005]JP-A 2005-88615 discloses an outboard engine which includes a clamp bracket ...
