I need help bad. I have a 1991 15 Hp Evinrude ouboard. A month ago I was crossing the lake and the moroe died about half way across. It wouldn't start again and I had to use the troppling motor to get back to shore. When i got home I pulled off the motor cover and found the fuel pump was leaking. I thought that might be the problem. I was wrong. I put the boat in today, it started right up and ran great. I boated around close to the ramp for a few minutes and the motor continued to operate just fine so I decided to go out on the main part of the lake. I ran the motor up to speed and was cruising just fine but then it happened. The motor speed started to slow down and then started it stopped. I couldn't get it started again. I smelled a faint odor that the motor might be hot but the fuel pump was working okay. It had a steady stream of water coming from the passage on the back of the motor. I could be wrong but I don't think it is the ignition because it was still firing good all the while the motor slowed down. The pump up bulb on the gas line was still hard so it must be getting fuel. I was wondering if the thernastat would cause this problem if it wasn't opening. Or what I should check first to see if I can locate the trouble. Any help will be greatly appreciated.
