Installation Notes

Before starting, ensure the engine is off and the battery is disconnected. Relieve all pressure from the hydraulic trim system.
Place absorbent pads under the old hose connections to catch any hydraulic fluid spills.
Carefully disconnect the fittings of the old hose from both the hydraulic pump and the reverse lock valve.
Remove the old hose and compare it with the new assembly to ensure an identical match in length and fittings.
Install the new trim hose, starting with the connection at the reverse lock valve and then attaching it to the trim pump.
Hand-tighten the fittings, then use a wrench to secure them firmly. Do not overtighten, as this can damage the threads.
Once installed, check the hydraulic fluid level in the trim pump reservoir and top off as needed with the manufacturer-recommended fluid.
Reconnect the battery and turn on the ignition. Operate the trim system up and down several times to bleed any air from the system.
Carefully inspect all connections for leaks and re-check the fluid level.

Troubleshooting & FAQ

How do I know if this trim hose fits my engine?

This hose is designed for a wide range of Mercruiser sterndrive models from approximately 1967 to 1993. The best way to confirm fitment is to check your engine's model, year, and serial number against the compatibility table on this page. Also, verify that your existing part's number is 32-58432A2, or an aftermarket equivalent like SIE18-2126 or GLM26220.

What are the signs of a failing trim hose?

Common signs of a failing trim hose include visible cracks, brittleness, or abrasion on the hose exterior. You may also notice hydraulic fluid leaks near the fittings or along the hose itself. Functionally, a bad hose can cause a spongy or slow trim response, or the sterndrive may not hold its trimmed position.

What is the function of this specific hose?

This trim hose is a critical component that transports high-pressure hydraulic fluid from the trim pump to the reverse lock valve. This process actuates the trim and tilt mechanism, allowing you to adjust the angle of the sterndrive for optimal performance and clearance.

How often should trim hoses be inspected or replaced?

It is recommended to visually inspect trim hoses at the beginning of each boating season and during regular maintenance checks. There is no fixed replacement interval, but any hose showing signs of wear, cracking, leaking, or blistering should be replaced immediately to prevent system failure on the water.
