Installation Notes
- Disconnect the battery and ensure the engine is off and cool.
- Trim the stern drive to the full "up" or "trailer" position for access.
- Carefully remove the old bellows clamps using appropriate tools.
- Cut or pull the old bellows from the transom and drive housings.
- Thoroughly clean the mounting surfaces on both the transom and drive to remove old adhesive, rubber, and corrosion. A clean surface is critical for a good seal.
- Apply a suitable bellows adhesive (not included) to the clean mounting surfaces.
- Slide the new bellows into position, ensuring it is seated correctly and evenly on both ends.
- Securely fasten the new clamps. Do not overtighten, as this can damage the clamp or bellows.
- Allow the adhesive to cure per the manufacturer's instructions before launching the boat.
- Lower the stern drive and inspect for proper alignment and a watertight seal.
Troubleshooting & FAQ
How do I know if this bellows kit fits my stern drive?
This kit fits Volvo Penta SX/DP drives (SX-S, SX-C, SX-R, SX-M, DP-S) and OMC Cobra drives (1986–1993), provided they do not have a cone clutch. Always cross-reference your existing part number with those listed in our Part Number Matrix.
What are the signs of a failing transom bellows?
Common signs include visible cracks, splits, or perishing of the rubber. A critical indicator is water entering your bilge, which suggests the bellows has been breached and requires immediate replacement to prevent catastrophic damage to the gimbal bearing and u-joints.
When should the U-joint bellows be replaced?
It is recommended to inspect bellows annually and replace them as part of regular preventative maintenance every 2-3 years in saltwater or 3-5 years in freshwater, or immediately if any signs of wear or damage are found.
Can I install this bellows myself?
While DIY installation is possible for experienced mechanics with the correct tools, we recommend professional installation. An improper seal can lead to major water damage to the gimbal bearing and U-joints.
