- Lower the stern drive to the full down position and place blocks for support.
- Turn the ignition off and disconnect the battery for safety.
- Place an oil-absorbent pad or container under the hose connection points.
- Carefully loosen the fittings at both ends of the old hose to relieve system pressure.
- Remove the old hose, noting its routing path.
- Install the new hose, ensuring it is not twisted or kinked.
- Hand-tighten the fittings, then use a wrench to tighten them securely. Do not overtighten.
- Refill the power trim pump reservoir with the recommended hydraulic fluid.
- Reconnect the battery and turn the ignition to the "on" position.
- Cycle the trim up and down several times to bleed air from the system.
- Check the fluid level again and top off as needed.
- Inspect all fittings and the hose for any signs of leaks.
Troubleshooting & FAQ
How do I confirm this hose fits my MerCruiser Bravo drive?
This hose is only compatible with Bravo drives with a serial number of 0W099999 or below. Please verify your drive's serial number before ordering.
What are the signs of a failing power trim hose?
Common signs include visible hydraulic fluid leaks around the engine or transom, a spongy or slow response from the trim system, or visible cracks, bulges, or abrasions on the hose itself.
Is this the "trim-up" or "trim-down" hose?
This hose connects the trim pump to the distribution block and is considered one of the two primary system hoses. Its specific function ("up" or "down") depends on the port it is connected to on the pump. Always consult your service manual for correct routing and connection.
What is the recommended replacement interval for trim hoses?
Inspect hydraulic hoses annually for any signs of wear, abrasion, cracking, or leakage. As a preventative measure, it's wise to replace power trim hoses every 5-7 years, even without visible damage, to avoid unexpected failure.
