Re: Only starts with Muffs
I have been having the same exact problem with my 1989 4.3 omc. Starts out of the water with the muffs, as soon as i put it in the water shuts down. However, I had the boat running fine so i thought, then noticed the smell of something burning. The flapper in the y pipe came off, no water getting to the manifold. After this is when the problem started of not running in the water. Took thermostat out and it was indeed stuck shut. Now would i be correct in saying that if the thermostat is stuck closed no water would get to the intake or the manifolds? All comments are appreciated.
