Yeah, it took me a while to ferret it out for sure. I had just had the head
rebuilt. ran fine but over heated. FInally the light went on in my head
and I solved
it. Some t-stats have a small hole in them I think. Maybe this engine didnt have the original stat. This was an 85 engine and this occurred in about 97-98. I discovered the boat for sale
again recently, and conversed with the buyer on the boat history
,,,,,still has the same Perkins in it and is running great. He bought it.
