Installation Notes

  1. Disconnect the vessel's battery and follow all standard marine safety precautions.
  2. Raise the sterndrive to the full "up" or "trailer" position and secure it with a drive lock or support block.
  3. Place an oil-absorbent pad under the hydraulic connections to catch any spilled fluid.
  4. Carefully disconnect the hydraulic lines from the trim cylinder. Be prepared for residual pressure and fluid release.
  5. Remove the retaining pins or bolts securing the old cylinder to the drive and transom assembly.
  6. Remove the old cylinder. Clean the mounting points of any debris or corrosion.
  7. Position the new trim cylinder and secure it with the original retaining hardware. Ensure it is correctly oriented.
  8. Reconnect the hydraulic lines to the new cylinder, ensuring fittings are clean and properly tightened.
  9. Refill the hydraulic trim fluid reservoir to the correct level as specified by the manufacturer.
  10. Reconnect the battery. Cycle the trim system up and down several times to bleed any air from the system.
  11. Check the fluid level again and top off if necessary. Inspect all connections for leaks.
  12. Remove the drive support and test the trim system for smooth and proper operation.

Troubleshooting & FAQ

How do I confirm this cylinder kit fits my specific Volvo Penta model?

The best way to ensure compatibility is to match your existing part number to one of the cross-references listed (872612, 872612-7, 3860978). You should also check your engine or drive model against the comprehensive 'Engine & Model Compatibility' table on this page.

What are the common signs of a failing trim cylinder?

Symptoms of a faulty trim cylinder include the drive slowly "drifting" down from the trimmed position, visible hydraulic fluid leaks around the cylinder seals or fittings, or a jerky or slow response when operating the trim/tilt controls.

Is this a single cylinder or a complete pair for both sides?

This listing is for a single trim cylinder kit. Sterndrive systems typically use two cylinders. If you need to replace both, you should purchase two units.

What maintenance is required for these trim cylinders?

Regularly inspect the cylinders for any signs of hydraulic fluid leaks, corrosion, or physical damage. Check the hydraulic fluid level in the reservoir at least once per season and keep the cylinder rods clean to prevent seal damage.

What is the difference between an OEM and an aftermarket part?

This listing is an aftermarket replacement, not an original equipment manufacturer (OEM) part. It has been engineered to meet or exceed OEM-level specifications using comparable materials and manufacturing processes. Our parts are produced in an ISO 9002 certified facility and are batch-inspected for quality and consistency.

How fast is shipping and what does it cost?

We ship worldwide quickly—typical transit time is 5–15 days. Standard shipping is free to most locations, with expedited options available at checkout where applicable. You will see final costs and delivery estimates before confirming your order.

What is the warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal marine use. Should an issue arise, please contact our support team with your order details for assistance. Returns are accepted within our standard window for unused items in their original condition. See our full policy page or contact us for instructions.

Safety & Important Info

  • Verify images and specifications against your original part before purchasing. If anything differs—even if your model appears on a compatibility list—do not purchase.
  • This is an aftermarket replacement part, not an OEM component. All mentions of brand names and part numbers are for reference purposes only.
  • Professional installation is strongly recommended for safety, proper function, and to prevent damage to the component or your vessel.
