Hello,<br /><br />This is my first time on the board and hope you can help.<br /><br />I have a 1983 9.9 Evinrude used on a small jon boat. Saturday, the water pump malfunctioned, unbehknownst to me, and while running at 3/4 throttle for 6 minutes, the motor ceased up and shut down immediately. It got so hot, the paint on the heat started smoking and turned brown. <br /><br />Though my mechanic, who has not seen the motor yet, said it will never be the same and it must be entirely rebuilt, I was able to get it started at home. I noticed the water pump still was not working but after a strong squirt up the pee hole, it started working and seems to run fine.<br /><br />I checked the compression and it was lower than it was 5 years ago, with the top cyl at 94 and the bottom at 108. My understanding is, less than 100 and a variance greater than 10% is bad. I have both problems. Still, it seems to run fine in the backyard, but I have not put it in the lake. IN the meantime, I have sprayed decarbonizer in the carb and on the pistons and am soaking it overnight. Thought this might help clean them up.<br /><br />I would appreciate your comments. Is this motor a problem waiting to happen? Will it perform poorly on the lake? What can i expect from it?<br /><br />thank you,<br />david
