The two happiest days in a boat owners life are the day he buys it and the day he sells it. Seriously though, selling an old glass tri hull is going to be hard to do. In my opinion you'd be better off selling the motor and trailer and giving the boat away with the trailer if you could. I'm in no way knocking your boat but there are a ton of old glass hull boats on the market and I see some of them parked in various places with signs on them saying boat and trailer $400.00, or $600.00 which is the actual value of the trailer by itself. Basically, if the trailer is in good shape, it will sell, the motor is in good shape-it will sell, the boat is in good shape-it might sell, it might not. Remember there is quite a power loss when you put a pump on a motor so you have to buy bigger and you know what that means $$$ Just my two cents...By the way why are boat motors so expensive?? I can get a lot ponies out of a small block chevy 350 for $10,000- a whole lot.
