It sounds like you had pistons out, cleaned up cylinder, freed up rings, the next thing I would do is take engine off the lower unit, take spark plugs off, check by hand if it goes into gear F-N-R, if that check’s out o-k, back to engine, with spark plugs removed, put one hand on flywheel, the other hand on PTO end, turn by hand at least 3 turns, checks o-k, install spark plugs, if that checks o-k, if not, get a 2×4 & dead blow hammer, hold 2×4 on PTO end of crank & tap fairly hard once or twice, if crankcase is not quite lined up yet, take flywheel off, & check other adjustments.
You mentioned you cleaned and scraped carbon off pistons & cylinder. Did you happen to use 847 grease on rod ends or elseware, that grease gets hard pretty fast, would make moving parts move hard. Next, did you make sure the pistons & rings were installed in correct cylinder & rod end marks lined up. Do you have a inch pound torque wrench, good tool for outboards. Gene.
