Installation Notes

1. Disconnect the battery and secure the boat and drive according to the service manual.
2. Relieve hydraulic pressure before loosening any connection.
3. Place absorbent material beneath the manifold and cylinder connections to collect fluid.
4. Photograph or note the original hose routing and identify the starboard “up” connection.
5. Remove the old hose carefully and inspect the mating ports and sealing surfaces.
6. Install the replacement hose without twisting, kinking or forcing the fittings.
7. Tighten the connections using the stern-drive manufacturer’s service specifications.
8. Top up the hydraulic reservoir with the specified fluid and bleed the system as required.
9. Cycle the trim system slowly and check for leaks before returning the boat to service.

Maintenance & Troubleshooting

Inspect the hose and nearby connections regularly for hydraulic-fluid leakage, abrasion, cracking, blistering, corrosion or damage from improper routing. A slow or spongy trim response, failure to hold the drive position or visible fluid loss may indicate a hose or system problem. Diagnose the complete trim system before replacing parts.
