Alden just hauled the engine out of the boat this afternoon and pulled it apart
Number 3 piston....number 4 in firing order, connecting rod failure at bearing / crank shaft journal with the lower piece of the connecting rod deformed...Looks like a bolt backed off. Removed the crank and I had a piston with rings and connecting rod that I gave him. I put that piston in and it went in with about as much trouble as a proper fitting set of rings should go, so I know that block wasn't bored.

Crank is scored pretty good on both inner journals but I had a good crank sitting there that I gave him. He put a gauge on the one that came out of it and the journals are smaller than the one I gave him. So the crank shaft coming out of the boat was machined and I believe the one I gave him came out of an original engine without ever being turned. I do know that engine he has was rebuilt about 10 years back and the crank must have been machined.

So, he's going to get in touch with MMI and get some bearings. Also told him he should get a machine shop measure both cranks so that he buys right bearings. Sounds like a major, but if we had the bearings for that it would go back in the boat in the morning. Sounds a lot worse than it was and he had that engine out of the boat in minutes today.
