Ok last time out this engine cut off after running about 2000 rpms for about 40 to 45min. It cut off and would not crank back up. Got back to the hill on the other engine (twin engines). When I got back to the dock still tried it never cranked but turned over strong. Then like 4-5 days later I pulled the plugs out of that engine replaced with new plugs. Then went to crank it but the engine would never turn over for me. There was a guy on craigslist that gave free estimates on repairs. He came out to me said man that motor is froze up tight. Checked the compression on my other motor he said nice this is a strong engine here. Said I can take it to my shop pull the head take a look it may just need a pistion. He said if up there looks ok it prob the crankshaft then you prob be better getting new motor a crank is 600.00. I said well not looking to sink alot into it. he said new engine run ya 1500-2000 cause when you get it its not ready to just slap in and go. I said well I prob sell it get what I can before putting that kind money in it. He calls few days later hate to tell ya this but when the motor locked up it got water inside of it the inside has rusted in there its shot "what would you like to do" another engine gonna run ya 1500-2000 I might can find someone who pic it up but prob not with the engine gone. One guy was like just cause the engine rusted inside dont mean its shot. Does that mean its shot guys????? The guy was like I think the guy trying to shaft you. Could it have just got to hot blew a head gasket or something and some water might have got in. Im get it back from him maybe get a second opinion from a friends boat mechanic. What you guys think your opinion. I know its hard being you havent saw inside the top of engine. Before it quit running I went through some low water water was muddy behind the boat when I tried to speed up thats why the only 2000 rpms for 45 min just tying to get back.

Thanks I appreciate any replies

only had boat year in a half only been out 5 times in it hate to know its done.

you will probably need to pull the engine,, clean the cylinders by honing them, replace the crank and possibly wrist pin bearings, but it should be ok after that

For real That would be nice Mechanic tell me 1500-2000 to ever get it running. Thats all that would need replacing how about pistions,rings,rod. I have the mentality of a 5hp briggs 4 stroke since I use to race go karts on dirt...Sorry

worse case- you do a rebuilt exchange with s b t probably easier than what you are doing and not a lot more expensive,, you will need to learn to remove the rear p t o and the front stator but it is not a big deal with the correct tools.

you need to tear into the motor and see what you really need. Apparently you sucked in water from somewhere. From the pics you are looking att pistons, rings, cylinder hone. Don't know about the crank, you have to take it apart and see. Cranks are pretty tuff though. I'd pull it apart ASAP to check the crank, and get it soaking in some type of penetrating oil. A crank that might be good today can start going to hell quick. the longer it sits rusting, the worse it gets.
