Abstract
A manually or magnetically operated selector valve for controlling the flow of hydraulic fluid through a hydraulic tilt and trim system of a marine outboard drive unit to achieve quick tilting up of the drive unit and slow trimming movement of the drive unit between a plurality of trim positions. The hydraulic system includes at least one fluid motor interposed between the marine vessel and the drive unit for adjusting hte tilt and trim of the drive unit. A reversible fluid pump and reversible electric motor are used to power the fluid motor. In the slow trimming mode, the pump delivers fluid to only one fluid chamber of the fluid motor while the fluid in the other chamber is discharged back to the pump. In the quick tilt up mode, fluid is delivered to both fluid chambers of at least one fluid motor simultaneously.
