[magnum28139]

hello,got a tough one to figure out..it's a1993 60hp evinrude,problem,at any time I can attach the ear muffs and engine will crank and run perfectly...but I can run 30 miles down to the lake and she wont crank,causing me to evitually flood her out..this has happened the last 3 attemps to go fishing,,there is new gas and the carbs where just rebuilt last week hoping this would help,,which it did;nt..thanks for any help..

Check to see if it has spark when it wont restart,could be ignition comportments breaking down..

Good idea. Weak ignition components tend to fail once the engine heats up to "normal" operating temps. Runs fine when cold-craps out when warmed up. So test for spark when the engine is well warmed up-could be a difference.

If the battery is weak the motor will not crank fast enuff to get spark.----If starter is weak the motor will not crank fast enuff to get spark.-------Get the battery checked / load tested.

I'm guessing the 30 Mile run is in the car so the difference is the motor starts fine on the muffs but not in the water?
Back pressure?

That's why I always work on mine in the driveway with a barrel. My poly barrel is the same height as the water line on the back of the boat, about 6" over the cat plate. Course you can't put it in gear....well you can but you won't have water after about 2 seconds lol. Also a bit of a pain to fill it and empty it if you have to raise the motor up.
