Abstract

A marine propulsion device comprising a gimbal housing adapted to be fixedly mounted on a boat transom, a gimbal ring pivotally mounted on the gimbal housing for pivotal movement relative to the gimbal housing about a generally vertical steering axis, the gimbal ring including a lower end, a support arm extending rearwardly from the lower end, and a generally horizontal cross-member extending across the lower end for preventing deflection of the support arm, a propulsion unit extending rearwardly of the gimbal ring and being pivotally connected to the gimbal ring for pivotal movement relative to the gimbal ring about a generally horizontal tilt axis, the propulsion unit including a portion extending adjacent the support arm for lateral support thereby, and a hydraulic cylinder/piston assembly pivotally connected between the gimbal ring and the propulsion unit for effecting pivotal movement of the propulsion unit relative to the gimbal ring about the tilt axis, the hydraulic cylinder/piston assembly having one end pivotally connected to the lower end of the gimbal ring for pivotal movement relative to the gimbal ring about a generally horizontal pivot axis.
