Looks too nice to scrap that powerhead. I’m with Mumbles, clean up the cylinder, find a decent used/new piston and rings, and off you go with a nice original engine. Those exhaust cover screws came out without a fight, so it must be a clean fresh water engine. I’m assuming you have had some OMC powerhead experience, so this job isn’t a big deal. Like others have said, be sure to measure the cylinder after cleaning it up, and don’t worry about removing every little scratch or gouge. Remember that honing the cylinder is really boring the cylinder, just at a much slower rate. I would prefer to have an imperfect (little scratches/gouges) cylinder that is still in tolerance (not out of round/oversize), than a clean cylinder that has been honed to oversize….Using the ball hone helps reach all the little imperfections.
You will know better what you have once it is apart and you have cleaned up the cylinder so it can be properly measured.
