70HP - Fried??

[stevemason]

Past weekend I had my boat out - ran well for a couple hours other than wanting to kill everytime I put it in gear. Usually took 5 or 6 tries to get it going. Heading back to shore wide open and it was like I hit a wall. Lost power and had to feather it back to shore. Pulled plugs last night and #1 plug had aluminum spatter on it. YIKES! I did a compression test and had the following:<br />Cyl 1 had 100<br />Cyl 2 had 110<br />Cyl 3 had 100<br />Is it possible that I did not ruin the engine?<br />I know I need to find out why it leaned out so bad on #1. I suspect that I overheated due to a failed impeller. This engine is a 1978 and not worth spending a lot of money on. Do you think since my compression appears to be good that I can get by with fixing the cooliing problem and run it? Or am I going to HAVE to tear the power head down. <br />Thought anyone?

Re: 70HP - Fried??

Suggest fixing the leaning out and cooling problems which would, hopefully, make it pick up the load when going into gear, then give it a chance with plenty of oil. Wouldn't go into powerhead yet with those compression readings! Good luck!
