Installation Notes
- Ensure the engine is off and the sterndrive is in a safe, accessible position. Place absorbent pads under the hydraulic connections to catch any spilled fluid.
- Carefully disconnect the old hydraulic hoses from the trim cylinders and the pump, noting their routing.
- Compare the new hoses with the old ones to confirm identical length and fitting types before installation.
- Install the new hoses, ensuring all fittings are tightened to the manufacturer's specified torque. Do not overtighten.
- Refill the hydraulic trim fluid reservoir with the recommended fluid type.
- Cycle the trim system up and down several times to bleed any air from the lines. Re-check the fluid level and top off as needed.
- Inspect all connections for leaks before returning the boat to service.
Troubleshooting & FAQ
How do I know if my trim hoses need replacing?
Signs of failure include visible cracks, brittleness, or blistering on the hose; fluid leaks at the fittings or along the hose length; or a spongy, unresponsive trim system. Regular inspection is recommended.
Will this kit fit my specific Volvo Penta 290-series sterndrive?
This kit is designed for the Volvo Penta 290, 290A, 290DP, SP-A, SP-A1, SP-A2, DP-A, DP-A1, and DP-A2 models. Always verify your model is on this list and that the part number 857624 is correct for your application.
Does this kit include hoses for both the up and down functions?
Yes, this is a complete kit containing two hoses, sufficient to replace both primary lines for the trim/tilt system on a single sterndrive unit.
How often should hydraulic trim hoses be replaced?
There is no fixed interval, but hoses should be inspected annually for signs of wear, degradation, or damage. Proactive replacement every 5-7 years is a common practice to prevent on-water failures, especially in saltwater environments.
What's involved in bleeding the trim system after installation?
After installing the hoses and filling the reservoir with hydraulic fluid, repeatedly run the trim all the way up and down. This forces air out of the lines and into the reservoir. Check and top off the fluid level as the air is purged until the system operates smoothly.
