If you were up front and realistic with him, then I don't see what the problem is. It's not like you said it was a diamond in the rough, just needing some paint to be brand new. If you swapped it out for rigging, then he should have known you didn't place much value in it. Honestly I would be offended if I traded an engine I was up front with running but being old and crusty and in overall rough shape, and they called me up months later saying it is low on compression so what are we goign to do. You sold him a used engine in rough shape, basically a part out engine. It doesn't sound to me like your in the wrong, but I would offer to take it back for the $500 just to keep from having any hard feelings. The lower unit if useable is worth $150-300, a stainless prop is worth $75-150, trim and tilt units working but ROUGH are worth an easy $100, and the rest should be worth an easy $250. He!! I've seen parts engines not running with holes in the blocks for more than $500 on craigslist here lately.
