As others have noted, these 22ci motors can be pretty forgiving. I once had a 1972 Evinrude 25hp that was stuck with rust in one cylinder. After freeing it up with penetrating oil, I tore it down and found some minor scoring in both cylinders and stuck rings on both pistons. I cleaned up the pistons, installed new rings and flex honed the cylinders. At that particular time, I didn’t have any OMC gel seal for the crankcase halves on hand so I used Permatex Motoseal (similar to the Honda bond or Yamabond) which seemed to work fine, but I think the anaerobic sealer is better. After reassembly and a run-in period, I had 130psi compression in both cylinders and it ran like new. I sold that motor several years ago and I’m told it still runs great.
