Installation Guide
-
Safety First: Trim the sterndrive to the fully "up" position and secure it with a trailering bracket. Disconnect the boat's battery.
-
Locate Hoses: Identify the four hydraulic hoses connecting the port and starboard trim cylinders to the connector block.
-
Release Pressure: Place a rag under the fittings to catch any fluid. Carefully loosen the fittings at both ends of the old hoses to release residual hydraulic pressure.
-
Remove Old Hoses: Once pressure is released, fully disconnect and remove the four old hoses. Note their routing paths.
-
Install New Hoses: Route the new hoses following the original paths. Hand-tighten all fittings first to avoid cross-threading.
-
Tighten Fittings: Securely tighten all fittings with an appropriate wrench, being careful not to overtighten.
-
Bleed the System: Reconnect the battery. Check the hydraulic fluid level and top it off if needed. Cycle the trim system up and down several times to bleed any air out.
-
Inspect for Leaks: With the system pressurized, carefully inspect all new connections for any signs of hydraulic fluid leaks before use.
Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: First, check the compatibility table to ensure your MerCruiser model and year are listed. This kit fits Alpha One (Gen 1 & 2), R, MR, and Bravo (1, 2, 3) drives. Second, confirm it replaces your existing part numbers, which should match 32-864959, 32-864960, or 32-99904Q2. The hoses are designed to work with trim cylinders that have casting #14035-1.
Q: What are the signs my existing hoses are failing?
A: Common signs include visible hydraulic fluid leaks around the fittings or along the hose, cracks or brittleness in the hose material, or a spongy and unresponsive trim/tilt system. Any of these symptoms indicate it's time for a replacement.
Q: Is this a complete kit for both sides of the sterndrive?
