Installation Notes

Disconnect the battery and ensure the engine is cool. Position the sterndrive in the full-tilt position for access.
Locate the lower exhaust bellows between the exhaust elbow and the Y-pipe.
Loosen and remove the two hose clamps securing the old bellows. A specialized bellows clamp tool may be required.
Carefully pry the old bellows off both connection points and clean the surfaces of any residue or corrosion.
Fit the new bellows into position, ensuring it is seated correctly on both the elbow and Y-pipe.
Secure the new bellows with the provided stainless steel clamps, tightening them to the manufacturer's specified torque to create a durable, watertight seal.

Troubleshooting & FAQ

How do I know if this exhaust bellows will fit my engine?

The best method is to verify your engine model and year against the compatibility table. Also, compare the OEM part numbers (32-14358T, 32-14358001) with your existing part or service manual. Visually matching the part to our photos is a good final check.

What are the signs that my current exhaust bellows is failing?

Common signs of failure include visible cracks or holes in the rubber, water in the bilge area (especially after running the engine), or an unusually loud exhaust sound. Regular inspection during maintenance is key to catching issues early.

How often should the exhaust bellows be inspected or replaced?

It is recommended to inspect all bellows (exhaust, u-joint, and shift cable) annually or every 100 hours of operation. Full replacement is typically recommended every 3-5 years, depending on usage (saltwater vs. freshwater) and storage conditions.

Can a leaky exhaust bellows cause major damage?

Yes. A significant leak can allow water to enter the engine bay and potentially flood the bilge, which could damage electrical components or even sink the vessel if left unattended. It can also cause the engine to overheat.

Is this part for the exhaust or the driveshaft?

This part is the lower exhaust bellows, which carries exhaust gases. It is different from the U-joint (driveshaft) bellows, which protects the universal joints from water. Both are critical components and should be inspected together.

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.
