Abstract
A system for controlling the movement of hydraulic fluid through the fluid containing chambers of a hydraulic cylinder operatively connected between a marine vessel and its outboard drive unit includes valves disposed within the cylinder to restrict the flow of fluid between the fluid chambers and a bypass for allowing unrestricted flow of fluid between the fluid chambers. The system includes a trim valve to allow limited flow of fluid in a first direction of piston movement and a tilt valve to allow unrestricted flow of fluid between the fluid chamber of the cylinder. A velocity sensing valve is provided to sense and prevent rapid upward movement of the drive unit.
