Installation Notes

  1. Safely secure the vessel and trim the outdrive to the full "trailer" or up position. Disconnect the battery.
  2. Locate and loosen the clamps on the old U-joint bellows.
  3. Carefully cut or pry the old bellows away from the transom shield and the outdrive.
  4. Thoroughly clean both mounting surfaces to remove any old adhesive, sealant, or debris.
  5. Apply a suitable marine adhesive (not included) to the mounting surfaces if recommended for your model.
  6. Slide the new bellows into position, ensuring it is properly seated on both ends.
  7. Securely tighten the new hose clamp. Do not over-tighten.
  8. Lower the outdrive, reconnect the battery, and check for any signs of leaks before operating the vessel.

Troubleshooting & FAQ

How do I know if this bellows kit fits my outdrive?

This kit is specifically for Volvo Penta SX and DP series drives, plus OMC Cobras, from 1986 onwards. The best way to confirm is to cross-reference your existing part number with those listed in our Part Number Matrix (e.g., 23075752, 22197130, 3854127, 983973).

What are the signs of a failing U-joint bellows?

Visible cracks, splitting, or holes in the rubber are clear signs of failure. Another common symptom is finding water or a milky, emulsified oil inside the bellows area upon inspection, which indicates a leak that is compromising your U-joints and gimble bearing.

How often should the U-joint bellows be replaced?

Most manufacturers recommend inspecting bellows annually and replacing them every 3-5 years as preventative maintenance, or immediately if any signs of wear or damage are found. Climate and usage (saltwater vs. freshwater) can affect lifespan.

Is any special tool required for installation?

Basic hand tools, including a screwdriver or socket for the hose clamp, are typically sufficient. A tool to remove the old bellows and a scraper for cleaning surfaces are also helpful. Some mechanics use a bellows expansion tool, but it is not strictly necessary.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?
