    Default 18' Alumacraft w/ Yam F90 jet

    18' Alumacraft (1860) w/ Yam F90/65 jet

    Anyone have any experience with this set-up? I'm working on buying it right now, and am wondering what kind of performance I'm going to get. Curious about how much weight it will push up the river (effectively), GPH on the 90 jet (at cruising speed) and cruising/top speeds.

    I read in another one of the posts something about 1 GPH per 10 HP, but 9 GPH seems pretty excessive for a mid-size boat and motor. Haven't been able to find a lot of info on-line about the motor's performance....so I'm looking for someone with some experience with this set-up.

    Thanks

    I have an 1860 G3 Outfitter Jon Boat with the 90/65 and get 6 GPH back and forth from Deshka Landing to Lake Creek. It doesn't seem to matter if I go light or load up with 1000 lbs...same fuel usage.
