It’s worth what someone will pay for it
an ‘02 hull and engine will have the value associated with the GW brand name. Engine I wouldn’t put a huge amount of value to.
imo probably in the range of:
hull and equipment - $10-20k
Engine - maybe up to $2-4k
Trailer - maybe up $2-4k depending on condition and options like SS brakes.
if everything is truly mint, turnkey, and you aren’t in a rush to sell I’d start pretty high to not leave money on the table, maybe even list at like $40k or even more, and gauge the market - it’s a sellers market for the past two to three years and it’s at the beginning of the season. I just think the older hull with an older engine wouldn’t fetch too much. Will depend on level of maintenance- if the fuel tank needs replacement soon, if there are any issues with electrical, if it has fancy gadgets, if everything is fully functional. Also where in the country you are and level of supply of comparable boats. There’s plenty of older hulls that still fetch big prices, but usually through a dealer providing a warranty for the engine and financing options.
