Abstract
Abstract An outboard motor attachment assembly comprises two assembly parts which are pivotally connected together, of which assembly parts a first part is arranged to be firmly secured to the stern transom of a boat and the second assembly part is provided with a support section for carrying the outboard motor. The angular position of the second part in relation to the first part is controlled by a control device acting upon a lever arm whose pivotal movement is limited by a stop on the second assembly part.

Claim 1
Independent Claim
222 words
An assembly for attaching an outboard motor to a boat hull, said assembly comprising: an attachment base affixable to the boat hull; an attachment housing having a support section for receiving an outboard motor; means for pivotably attaching said attachment housing to said attachment base so that said attachment housing is angularly positionable about a first, approximately horizontal axis; a lever arm having a first end and a free end; means for pivotably attaching said first end of said lever arm to said attachment housing so that said lever arm is pivotable about a second, approximately horizontal axis; stop means fixed to said attachment housing for limiting the pivoting motion of said lever arm; controlled means connected to said lever arm at a location between said free end and said first end for selectively adjusting the angular position of said attachment housing, said controlled means adjusting the angular position of said attachment housing according to trim by pivoting said lever arm about said second axis with said free end in contact with and moving along said boat hull between a first lever position spaced from said stop means and a second lever position adjacent said stop means, said controlled adjusting means adjusting the angular position of said attachment housing to a tilting position by urging said lever arm against said stop means.
