U-Joint Bellows – Fits Volvo Penta SX/DP-S & OMC Cobra (Replaces 22197130, 23075752)

This is anreplacement U-joint bellows designed for a wide range of Volvo Penta SX and DP-S series sterndrives (1994–Present) and OMC Cobra clutch dog models (1986–1993). It serves as a direct replacement for multiple OEM andpart numbers, including Volvo Penta 23075752 and OMC 3854127.

The accordion-style flexible boot design accommodates engine and drive movement while maintaining a critical watertight seal around the universal joint. This protects sensitive drivetrain components from water intrusion.

Installation Guide

1. Safety First: Before starting, disconnect the battery and ensure the sterndrive is securely trimmed up and supported.
2. Access the Bellows: Depending on your model, you may need to remove the sterndrive from the transom shield to access the U-joint bellows.
3. Remove Old Bellows: Loosen and remove the hose clamps securing the old bellows at both the transom and drive ends. Cut away the old bellows if necessary, being careful not to damage the housing surfaces.
4. Clean Mating Surfaces: Thoroughly clean the mounting surfaces on the transom shield and sterndrive. Remove any old sealant, rubber residue, or corrosion to ensure a clean, smooth surface for the new bellows.
5. Install New Bellows: Apply a suitable bellows adhesive to the cleaned mounting surfaces. Slide the new bellows into position, ensuring the larger end connects to the transom shield.
6. Secure Clamps: Position the new stainless steel clamps over the bellows ends and tighten them securely. Ensure the clamps are straight and provide even pressure.
7. Reassemble & Test: Reinstall the sterndrive if it was removed. Once fully assembled, lower the drive and check for any water leaks around the bellows before operating the vessel.

Troubleshooting & FAQ

Q: How do I know if this bellows will fit my sterndrive?
A: Check your model and year against the compatibility tables. This part fits Volvo Penta SX/DP-S models from 1994-Present and OMC Cobra (clutch dog) models from 1986-1993. Verifying your OEM part number against our cross-reference list (e.g., 23075752, 3854127) is the best way to confirm fitment.

Q: What are the signs that my u-joint bellows needs replacement?
A: Look for visible cracks, splits, or perishing of the rubber. Water inside the bellows or a grinding noise from the universal joint area during operation are also critical indicators that the bellows has failed and needs immediate replacement to prevent catastrophic damage to the drivetrain.

Q: How often should I inspect or replace the U-joint bellows?
A: It is recommended to inspect the bellows annually or every 100 hours of operation. Replacement is typically advised every 3-5 years, depending on usage (saltwater vs. freshwater) and environmental exposure, even if no visible damage is present.
