Troubleshooting & FAQ
What are the signs my exhaust bellow is failing?
Common signs of a worn or failed exhaust bellow include water leaking into the bilge area, an unusually loud exhaust noise, visible cracks or splits in the rubber, or the bellow becoming soft and spongy to the touch. It's a critical part to inspect annually.
Will this fit my 1985 MerCruiser 205 HP V6?
Yes, this exhaust bellow is listed as compatible with the MerCruiser 205 HP V6 model for the years 1985–1987. Always double-check your model and year against the full compatibility list before ordering.
Is this bellow resistant to saltwater?
Yes. It is manufactured from Chloroprene (CR) rubber, a material specifically chosen for its good resistance to seawater, heat, and ozone, making it suitable for marine environments.
How often should I inspect the exhaust bellow?
It is best practice to inspect all sterndrive bellows, including the exhaust bellow, at least once a year during regular maintenance. If you operate in saltwater or harsh conditions, more frequent inspections are recommended. Replace it at the first sign of wear or damage to prevent water intrusion.
