Long story short, had to take the exhaust manifold plates in and the marine mechanic sanded them as they were warped a bit. i had the block off to do the work and check for any water in the block and such. he looked at the sides of the pistons and walls and said yikes, how long do you plan on running this motor. in other words he said you might get a few hours or a few years as to how bad he thought the scoring was on all 3 cylinders where i thought it wasnt that bad due to my decent compression readings. he figured compression can be misleading. so, with the scoring on the walls and decent compression, is it worth a rebuild and if it is, this would be a fun winter project for me with all the work i did on it. obviously, i didnt put it back together at this point so just packing up the boat for the winter. in my neck of the woods, not alot of used motors around except if you buy the whole boat. i know i could do it cheaper than an $8000 new motor. the mechanic said $1800 with a 1 year warranty on his rebuilt.
