Re: 76 evinrude 15 thermostat?
I just did mine on my mid 80's 15hp. I could not get the water cover jacket off or the cowl latch off so I had to remove the head first. A little more work but it worked fine. I also reused the head gasket, I spread a thin film of gasket sealer on it and it worked fine also. Most folks will say that's a no-no but i have it many times with never a problem.
