Abstract
The power steering and trim functions of a marine drive unit are combined in a fluid pressure supply system which utilizes a single electric motor drive hydraulic pump to provide operating fluid for both functions. Fluid pressure to operate the power steering is supplied by an accumulator which, in turn, is charged by the hydraulic pump. The pump is also operable in response to operator input to supply fluid pressure for the trim system. Appropriate controls, responsive to the upper and lower pressures limits of the accumulator, are used both for charging the accumulator and for providing operational priority to the power steering system by disabling operation of the trim system during charging of the accumulator.
