Abstract
A tilt and trim assembly for tilting an outboard drive includes an improved construction. The tilt and trim assembly has an outer cylinder defining a first internal cavity, a tilt cylinder slidably supported in the cavity and defining a second internal cavity, a tilt piston slidably supported within the second cavity and a piston rod affixed to the tilt piston and extending beyond the cavities. In one aspect, the tilt and trim assembly further has a latching mechanism to lock the tilt cylinder at the fully tilt up position. The latching mechanism includes a first engaging section defined directly at the tilt cylinder and a second engagement section defined at the outer cylinder. The tilt cylinder directly receives the tilt piston when it is placed at the deepest position. In another aspect, a lower section of the outer cylinder is thicker than an upper section thereof. A pressurizing mechanism is provided for pressuring working fluid in the cavities and has a powering assembly therein. The powering assembly is disposed in proximity to the upper section of the outer cylinder.
