Troubleshooting & FAQ
How do I confirm this bellow fits my engine?
Verify your engine is a MerCruiser V6 or V8 model from 1986 or newer with a center rise exhaust. Cross-reference your existing part number with those in the Part Number Matrix above for the surest fit.
What are the signs of a failing exhaust bellow?
Common symptoms include visible cracks or splits in the rubber, water entering the bilge area, or a noticeable increase in exhaust noise from the stern drive area.
Are clamps included with this bellow?
No, clamps are not included. This bellow requires four 5-inch hose clamps for a complete installation.
How often should this part be replaced?
Exhaust bellows should be inspected annually for cracks, stiffness, or signs of wear. Replacement is typically recommended every 3-5 years or as part of routine stern drive service, depending on usage and water conditions (salt vs. fresh).
What's the difference between this and an OEM part?
This is a high-quality aftermarket part manufactured to meet or exceed OEM specifications. It provides the same performance and fit as the original but at a more accessible price point.
Should I replace any other parts at the same time?
It is best practice to also inspect and, if necessary, replace the U-joint and shift cable bellows when servicing the exhaust bellow, as they have similar service lives and require disassembling the same general area.
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.
