1973 65 HP Evinrude dies

jgmilberg I have a 1973 Evinrude Triumph 65 HP 3 cylinder, w/ selectric shift. The problem I have is that after about 20 to 30 minutes of flat out running the motor just quits. If we remove the cover and let it sit for 15 minutes the motor will re-start and run, 2002-04-29
J.B. Cornwell Howdy, JG.

Your best bet is to troubleshoot when the engine is misbehaving. Try to find a shop that has a dynamometer to put it under load.

If that isn't possible, heat the ignition components one at a time with a hair dryer or heat gun while it idles on the muffs.

I think you probably have a powerpak problem, but I agree with you that you should prove it before spending the bux to replace.

Good luck. [Smile]

jgmilberg JB- I pulled the coils off today, and all of them are cracked. The power pack doesn't look like it's melted down or discolored. I was told that the power pack would either work or not work, and I do get a good strong spark when it's cold, but after warmed up the spark looks more yellow than blue. Do you still suspect the power pack or do you think that the coils are cooked. Will a bad coil(s) fry a power pack?

Thanks [Cool]

i happen to have the same motor. when my powerpack went out everything shut down. and when you say that it will sometimes run on 2 cylinders ,,,,,be careful,,,,,i believe that led to me slinging a rod out the side of mime. i really loved that motor.

Whatever is failing isn't failing until the engine is hot. That is a common powerpak trouble. Try the hair dryer.

Good luck. [Smile]

jgmilberg I took the coils and power pack in to an Evinrude dealer to see what was going on, they said it was not a goos idea to run the cracked shell coils, and they can not test the power pack w/o it being on the boat. They wouldn't even look at the coils to thi 2002-04-30
