ABSTRACT:
A compact, integral hydraulic power assembly is provided for mounting above the flywheel of an outboard marine engine. The hydraulic pump couples in coaxial alignment with the crankshaft of the engine. The hydraulic pump is surrounded by an annular hydraulic fluid reservoir with a cooling element having a channel for flowing cooling water to cool the hydraulic fluid. A special rigid coupling between the pump shaft and the flywheel/crankshaft and a resilient coupling of the reservoir housing to the engine ensures correct alignment without adjustment.
