Question
Exhaust bellows - overheating

I have a 1990 four winns 205 sundowner, with a 302ci ford in/out mercrusiser. recently, while on the water and hooked-up, I had a bellows on the exhaust system, overheat, and fail. Luckily, made it back to shore. but, why would it overheat? engine @150 temp, and ok. oil pressure @40+, and ok.

Submitted by: gibsonsmth7
Answer

The most common issue is a clogged manifold or riser not allowing enough water to mix with your hot exhaust causing this problem. Mercruiser did not use a Ford powerplant in 1990 so you either have an OMC or Volvo drive. If you give the appropriate engine information we can look up the parts you need.
