What This Trim Motor Reservoir is Used For
This trim motor reservoir assembly is used on compatible hydraulic power trim systems to drive the trim pump and hold trim system fluid.
The trim motor powers the hydraulic pump that raises and lowers the sterndrive or outboard during trim and tilt operation.
A failed or weak trim motor may cause slow trim movement, intermittent operation, clicking with no pump movement, or complete trim system failure.
Replacing the motor and reservoir assembly can help restore proper trim system operation when the original unit has failed and the pump valve body is still serviceable.
