ABSTRACT:
A hydraulic assembly for use with a marine propulsion device including a bracket adapted to be mounted on a boat and a propulsion unit pivotally mounted on the bracket, the hydraulic assembly comprising a cylinder/piston assembly including one end adapted to be connected to the bracket, an opposite end adapted to be connected to the propulsion unit, a generally flat first mounting surface, and a passage communicating with the mounting surface, a reservoir having a wall which is formed by blow molding and which includes a tank portion defining a cavity adapted to contain hydraulic fluid, a mounting flange having thereon a generally flat second mounting surface and having therein an orifice, and a neck portion defining a passageway communicating between the cavity and the orifice, the passageway having a reduced cross-sectional area relative to the cavity and having an increased cross-sectional area relative to the orifice, a sealing element, and structure for mounting the reservoir on the cylinder/piston assembly so that the mounting surfaces are in mating engagement, so that the orifice communicates with the passage, and so that the sealing element is clamped between the mounting surfaces and surrounds the orifice and the passage.
