Hello, I have a 1975 OMC 140 engine. The cap on the back of the manifold where the water comes in and cools the exhaust was leaking. I took it off and the gasket was all ripped and mostly not even there. I was wondering if I could use some waterproof silicone to put it back on until I can get another gasket. Also, what kind of damage would occur if the water leaked into that middle section that the exhaust goes through.
Thank You in advance!!!
