Can anyone offer me advice. I am a student at the Marine Mechanics Institute. I was approached by someone to repair their 1985 8hp Suzuki. Upon inspection I found that it needed to be rebuilt ( new piston, rings, cylinder hone, carb rebuild, water pump replaced). I informed him that I would gladly do it but I told him honestly that it would really not be worth it and that it may be cheaper to replace the motor with a different one. He said he would look for one. A couple of weeks went by and I started leaving him messages, but he never returned my calls. this was 3 months ago and last week I posted it for sale and have since traded the motor for other things. He saw my post to sell the motor and called me demanding the motor back. Has anyone out there, maybe shop owners, been in a similar situation, and what can I do about this?
