I have a 1973 Evinrude 115 HP. When cold i have to play with the chock but starts after 5-6 tries i can run for 2-3 hrs at WOT with no problems but if i shut it off I can get it to idle for 5-10 then stalls and wont start and run.. I can drive from lake to house about an Hr drive and put muffs on motor and it will start and run fine.. Any idease would be thankful..:confused:

Thanks Again

Have you checked to see if you are loosing spark when it won't start hot? Could be carbs leaking fuel when you shut it off and flooding the engine. You're going to do some investigating.

I haven't checked spark, i was on lake twice when this happen had to get towed both times didn't have any testers.. I did the Sea Foam cleaning at home like recommended in the forums and the motor ran for about 2 hrs then i shut it off waited about 5-10 min and it started right back up so is running it on muffs or not at WOT not getting it warm enough to cause the problem because the only time it has happened is on the lake..

Thanks

Basically you are going to check it out when the problem occurs. Take some tools and go for a boat ride. Maybe a friend that has a boat will go along, or see if you can borrow a small kicker engine in case it lets you down again.
