No compression in cylinder on 60 hp.
I got a friend that has a 1990 or 91 evinrude 60 hp 3 cylinder. We were out the other day for the first time this year and it ran fine. Coming back to the ramp it died like it was out of gas. He would restart it and it would run a couple hundred yards and then die again. He checked the compression and it has I think 120lbs in the top and bottom cylinder's and 0 lbs in the middle one. What does this sound like?

At 0 compression, I'm thinking a trashed cylinder that wasn't getting fuel...

Hopefully a blown head gasket is all it is, thanks guy's.

Very likely a scored piston from overheating or running lean.
There were several service bulletins back in the motor's day for rejetting, retiming, heavy duty water pump, and repositioning the water tell-tale fitting to help bleed air out of the cooling system to prevent future problems.

It was a stuck needle valve in the middle carb. Once it pumped all the gas out of it, there was no more gas and oil going into the cylinder. It scored the cylinder wall pretty bad. He's going to hone it out some and get oversized ring's and see what happen's!
