my tahiti with roadrunner trailer, same length mini day cruiser with stock 460 bbf tipped in at 3800. that was with a little bit of fuel in boat and wet/rotted wood. i pulled it to scale with my 4cyl. s10. which i wouldnt recommend.
weigh it to be sure...this way youll know what you have to play with. scale by me was also 10 bucks.
