    90 has been done, it's to heavy for a reg size racer, i am settin up my shop for jobs. this season is gone. 90hp needs bigger reed blocks to make it really go,,,,,,,,,,,,,

    This boat is made for a 20" I would like to make a 90 into a 15" and save more #s and lower the cg possible jackplate and hydraulic steering fall winter project I thought e-fuel could be done? This hull with a stock 90 will do 70+0r- with the right tweaks this could be a hard launching plenty fast sleeper!

    they made 1:71's , 1:85"s in a small foot, like the Nitro and a ski foot with 2:30's . you want the small foot 1;85's seems the best all around

    Hey fred when you dis the yamarude conversion how did you overcome the lengh of the shaft into the yamaha swivel.
    I just pulled mine down to trial fit and found its not long enough to get the circlip on the lower of swivel shaft ?
    Did you take some meat off the top where there is some free metal to be removed ?
    Thanks lindsay
