Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: The surest way is to match your engine's model and serial number to the ranges listed in the compatibility tables above. Also, verify your exhaust system has a 4-inch inside diameter at the connection point between the riser and elbow.

Q: What are the signs that my exhaust bellow needs replacement?
A: Common signs of failure include visible cracks, brittleness, or perishing of the rubber. You may also notice water leaks in the engine bay or an unusually loud exhaust sound, indicating a leak.

Q: How often should I replace the exhaust bellow?
A: It is recommended to inspect exhaust bellows annually for wear and tear. Replacement intervals depend on usage (freshwater vs. saltwater) and operating conditions, but they should be replaced immediately if any signs of damage are found.
