Installation Guide
-
Safety First: Turn off the engine and disconnect the battery. Relieve pressure from the hydraulic system by lowering the drive completely.
-
Prepare Work Area: Place absorbent pads under the hydraulic connections to catch any spilled fluid.
-
Locate the Hose: Identify the correct trim hose running from the trim pump to the distribution block.
-
Disconnect Old Hose: Using two wrenches (one to hold the fitting, one to turn the nut), carefully disconnect both ends of the old hose. Be prepared for fluid leakage.
-
Remove Old Hose: Once disconnected, carefully remove the hose from its routing path.
-
Verify New Part: Compare the new hose to the old one to ensure the length and fittings are identical.
-
Install New Hose: Route the new hose correctly, ensuring it is not twisted, kinked, or rubbing against any sharp edges.
-
Tighten Fittings: Hand-tighten the fittings, then use wrenches to secure them. Do not overtighten, as this can damage the fittings or hose.
-
Refill and Bleed System: Top off the power trim fluid reservoir with the manufacturer-recommended hydraulic fluid.
-
Reconnect Power: Reconnect the battery.
-
Test for Leaks: Cycle the trim up and down several times to bleed air from the system. Carefully inspect all connections for any signs of leaks.
-
Final Check: Re-check the hydraulic fluid level and top off if necessary.
Troubleshooting & FAQ
Q: How can I confirm this hose fits my MerCruiser drive?
A: This hose is designed for MerCruiser R, MR, Alpha One, Alpha One Gen II, and Bravo stern drives. For Bravo drives, it is crucial to verify your serial number is 0W099999 or below. Always compare the part numbers (Mercury 32-861128/32-95859, Sierra 18-2436, Mallory 9-71512) and the hose length (51") to your existing part.
Q: What are the signs that my power trim hose needs replacement?
A: Common signs include visible fluid leaks around the hose or fittings, cracks or bulging in the hose material, a spongy or slow-responding trim system, or a frequent need to add hydraulic fluid. Any visible damage warrants an immediate replacement to prevent system failure.
Q: Is this the only hose I need to replace for my trim system?
A: Power trim systems typically have multiple hoses (e.g., up and down pressure lines). This part replaces the specific hose connecting the trim pump to the distribution block. It is good practice to inspect all hydraulic lines for wear and tear when replacing one component.
