    1200 npv

    hey guys i have gp 1200 that is doing 59.1 on gps but the bottom has alot of damage done to it so its slowing me down I was thinking of putting my engine into a regular xl hull and doing a few pump parts such as
    • ride plate
    • extended nozzle
    • prop
    • sponsons
    do you think i will loose much speed seeing as this hull wieghs more or will I gain seeing as this hull has much smother bottom ?

    Well 59.1 is not that bad if the GP is stock. What year is the GP? The XL is going to be a slower hull than the GP in smooth water.

    +1 BUT, the XL is like a battleship in the rough stuff. I mean 3 foot waves can be called "chop" on that monster. they both have there place though.

    on my gp1200 i managed probably 45 in rough stuff. 1/2 because I was scared, and the other 1/2 was because the thing thought it was a plane. it was always vertical. it would run 65 or so on flat water modded.

    a stock 1200 in the xl should run around 55 ish.

    A stock GP is only going to do 61 at best in perfect conditions. Why don't you take a few pics? Most stock GP's run 59-60 bone stock.

    I will be repairing the bottom of the hull with gel coat and paint the whole ski black with the full hood red and red seat
    Krispaintballs is giving me some parts that will keep me from switching form my gp
