We picked up a 21foot eliminator Daytona. We bought for hull it came with a 225 1986 Evinrude on it. We have lots of experience with jets and big blocks LOL not outboards
The boat had been run in salt water a lot and has sit out side not used for 7 years or so.
After fixing all the wiring and successfully freeing up motor (wasn’t badly stuck) we were a bit shocked it had spark and 70-90 lbs of compression. (Low in 2 cylinders at 70/73). We of course mixed up some fuel by specs and it fired right off. We then hooked to hose and ran 1-2 gallons of gas through it. Monitoring temps and general things. We were a bit shocked how good it sounded and was running. Turn it off come back hour or two fired right up. Did compression check and low cylinders came up about 5 lbs each other’s close to 90. We mixed up more gas (this process was over 2-3 days ) we started it up. And nearly ran another gallon of fuel and it abruptly shut off. The gallon jug was empty so although it stopped abruptly (no sounds no missing just stopped quickly) we went to start and it wouldn’t turn over. The starter was stuck in flywheel and we were pissed thinking starter just broke and it’s brand new would not disengage. We took it off and then found the motor wouldn’t turn over. It would only turn a 1/8 of a revolution one way then back the same. It would hit metal on metal one way. We took plugs out got long screw driver and gently put in each cylinder and by hand rotated motor. We could feel pistons moving but 1 seemed like it wasn’t the same. But couldn’t tell. Took off that head and really couldn’t tell anything as it wasn’t a ring (feeler gauge and card stick we
Could feel ring and the metal on metal was a solid sound ) piston moved but slightly so we took other head off and when we did the motor turned over nearly a 1/2 to 2-3 rotation. Each pistons get to nearly top dead center then it hits metal on metal turn back and same. You can see all the ports and nearly all I was able to run a snake camera down the ports. Could see numbers on rods and nothing jumped out. Maybe I thought the wrist pin bearings maybe came out of cylinder 1 and maybe that would let wrist pin slide and it gets hung on bottom of port or cylinder wall. It is a very solid metal on metal. The motor doesn’t have any apparent damage on top other than rusted head gaskets and number 4 has very minimal scaring on the wall but not new. Slight signs of detonation on the piston ( was also lowest compression at 70) but nothing new. To make matter worse 2 head bolts broke with only about 1/4 inch sticking above the motor deck. No luck yet getting them out. Any suggestions appreciated. I have a video of the turning of motor by hand if I am allowed to post. Will post a few pics first. Any thoughts on what happened? Rebuildable ? Worth it? Don’t think rod broke ( unless partially nor do I think crank broke all clyniders move the same. Thank you and sorry for long post just trying to be detailed.
