Seafoam might help some. Does it sound like it's "coughing" or spitting at idle sometimes? Mine did that and I replaced the head gaskets and cleaned the carbs. Glad I did, too...one of the head gaskets was getting bad.

If you do it ( it's easy)...make sure you replace the little rubber tubes in the water jacket while you're in there. I forgot what they're called, but they ARE necessary for proper cooling.

Yes it does , almost kills engine but it picks right back up...on that head gasket note I did notice a drip coming from the left side of engine that I assumed was a leaking gasket

Buy a repair manual to get the headbolt torque specs and tightening pattern.

You have a lean sneeze run it with the Sea Foam. I would not just jump in and try to change head gaskets. Too many problems can jump up, like the head bolts being stuck. You can run the motor on a cuff or at the lake with a sparkplug out, cover the sparkplug hole about 6in. away with cardboard while running. If you are getting water it will bead onto the cardboard. Do each sparkplug one at a time. It is normal to see a sparkplug with a chalk white coating on the cylinder with the water leak.

Next step is seafoam and cardboard test on the hose then take it to the lake again and run it some more Ill report back in a few days

Did the seafoam and ran it and it did pretty good seems to be getting better the more it gets ran .For now I'm gonna just use it and go with the if it aint broke don't fix it theory Now its time to move on to my other evinrude headache Ill start a new thread for it if needed .Thanks for all the help everyone

Good Deal

I found a tiny spot of rust ( miniscule) on one spark plug on my old 'Rude....that's what prompted me to go ahead and swap out the head gaskets. Besides, I had nothing better to do that weekend.

'Glad the seafoam is helping a little.
