Abstract

A mount for a boat propulsion unit comprises a collar for mounting around an aperture in a boat's hull, the collar having an annular groove on an inner surface thereof; a first mating part for mounting an inboard portion of a propulsion unit to the boat; and a second mating part, connectable to the first mating part, for mounting an outboard portion of a propulsion unit to the boat. The first and second mating parts are connectable through the collar and are configured such that when they are connected they form an external annular recess in an outer surface and an annular gasket is located partly in the groove and partly in the recess to form a seal there-between.

Description

FIELD OF THE INVENTION

[0001] This invention relates to a mount for a boat propulsion unit. Particularly, but not exclusively, the invention relates to a mount for mounting an inboard propulsion unit in a boat hull.BACKGROUND TO THE INVENTION

[0002] Aspects of the present invention are particularly concerned with the mounting of electric propulsion units that consist of a saildrive projecting from the bottom of a boat's hull and that have an inboard motor mounted above the saildrive. In essence, a saildrive can be considered as a sailboat's equivalent of a motorboat's sterndrive, which projects from the stern of a boat and usually has a drive mounted outside of the hull (and is therefore also known as an outdrive). A saildrive is significantly different to a traditional inboard motor since it is not connected to the motor via a standard propeller shaft. Instead, inside a saildrive casing there is normally an L-gear that consists of a vertical (pinion) shaft, a horizontal (propeller) sha...
