Installation Guide
- Disconnect the battery and relieve hydraulic system pressure before beginning work.
- Locate the existing trim/tilt hose running between the hydraulic pump and the transom connector.
- Place a drain pan beneath the work area to catch any hydraulic fluid.
- Carefully disconnect the hose fittings at both the pump and transom ends. Note the orientation and routing of the original hose.
- Remove the old hose and inspect the fittings for damage or corrosion.
- Install the new hose, ensuring fittings are properly threaded and seated at both connection points.
- Tighten the fittings to the manufacturer's torque specifications (typically hand-tight plus 1/4 turn with a wrench).
- Route the hose along the same path as the original, avoiding sharp bends or contact with moving parts.
- Refill the hydraulic reservoir with the recommended trim/tilt fluid to the proper level.
- Reconnect the battery and operate the trim/tilt system through its full range of motion several times.
- Check all connections for leaks while the system is under pressure. Tighten fittings if necessary.
- Verify proper trim and tilt operation before returning the boat to service.
