I'm a yachtie but just found a ski boat , 18' with new mariner 175, on twin axle snipe trailer.Really good condition, £2000. Does that sound cheap? Guy reckons it does 75mph?
If the mariner is new, which I doubt, it alone would be worth more than £8k, because the 150 hp costs that, and they don't get cheaper the bigger they get,
the snipe twin axle trailer, even if old but in good working condition would make £1k
so if the boat was made of cardboard you wouldn't be on a loser
