Abstract: A marine engine assembly has a housing including an outer housing having a front wall, an inner housing disposed in the outer housing and being connected to the outer housing by at least one housing fastener disposed at at least one first position, a cover removably connected to the outer housing, and a gearcase connected to a lower portion of the outer housing. An internal combustion engine has a front face connected to and supported by the inner housing by at least one engine fastener disposed at at least one second position being different from the at least one first position, and a crankshaft defining a crankshaft axis intersecting the front wall of the outer housing. The inner housing is disposed at least in part between the front face of the internal combustion engine and the front wall of the outer housing.

Abstract: A drive unit has an engine, an operatively connected driveshaft, a transmission, and a propeller shaft connected to a rotor outside a gear case. A plate, extending above the rotor, is adapted to slidingly receive along a joint axis, an accessory having an accessory joint element which is one of a channel and a protrusion. Extending parallel to the joint axis along a plate joint surface, which is one of a first surface facing away from the rotor and a second surface facing toward the rotor, is a plate joint element, which is the other of the channel and the protrusion, adapted to slidingly interlock with the accessory joint element to thereby prevent displacement thereof in a first direction parallel to the plate joint surface and perpendicular to the joint axis, and in a second direction normal to the plate joint surface. An accessory attachment method is also disclosed.
