Installation Notes

  1. Ensure the engine is off and the boat is safely secured. Disconnect the battery.
  2. Tilt the sterndrive to the full "up" or "trailer" position to access the exhaust bellows.
  3. Loosen and remove the clamps on both ends of the old bellows.
  4. Carefully pry the old bellows off the exhaust pipe and the sterndrive housing. Clean the connection surfaces thoroughly.
  5. Position the new bellows, ensuring it is properly seated on both the drive and transom pipe.
  6. Securely fasten the new stainless steel clamps on both ends. Do not overtighten.
  7. Lower the sterndrive and check for proper alignment and any potential binding.
  8. Reconnect the battery, start the engine, and check for exhaust leaks around the new bellows.

Troubleshooting & FAQ

How do I know if my exhaust bellows needs replacing?

Common signs of failure include visible cracks, perishing rubber, water leaking into the bilge (especially when the drive is trimmed up), or an unusually loud exhaust note. Regular inspection during maintenance is key.

Can I install this myself?

While DIY installation is possible for those with mechanical experience, professional installation is recommended. It ensures proper sealing and avoids potential damage to the sterndrive or engine from water ingress.

What is the difference between this and the OEM part?

This is an aftermarket part designed to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It uses comparable marine-grade materials for reliable performance at a better value.

How often should exhaust bellows be replaced?

Replacement intervals vary based on usage, water conditions (salt vs. fresh), and exposure to elements. A general guideline is to inspect them annually and replace every 3-5 years or at the first sign of wear.

Will this fit my specific boat model?

This part fits the engine and sterndrive models listed, regardless of the boat brand. The critical factor is matching your Volvo Penta engine/drive model number, not the boat manufacturer.

Is any special tool required for installation?

Typically, only standard hand tools like a socket set or screwdriver are needed to remove and tighten the clamps. A pick or flat-head screwdriver can help remove the old bellows.

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.
