OMC 2.3 Block.. has overheated but didnt seize or anything, head wasnt cracked , had it rebuilt
The thing is the #4 cylinder has a ring in it its not perfectly straight line its jagged making me thing its an indication of a crack that let some crap in and rubbed it into the wall, but ya cant see an actual crack and it feels smooth... and it goes all the way around so i would think it would fall apart if it was a crack..
everything i can find about cylinder inspections is about scratches that are vertical.. this looks like someone took a broad tipped pencil and drew a line all the way around the cylinder..
Thought about rubbing on it with some 800 sandpaper to see what happened but i have never seen or heard about anything like this and cant find any info online.
At this point i figure Black line = bad no matter if i can identify its cause or not, but if the block isnt cracked and is usable i wanna d that..
Thought about putting a 1/4" sheet of plexiglass on it and bolting it down with some sealer and pumping like 80 psi or so nto it and let it sit awhile and see if it holds air... I dont know what is involved for a shop to check it but i have too much money in a 4500 dollar boat already so trying to get it running reliably so i can keep it or at least have the option to sell it for anything but salvage..
