    mph low???

    Hi All,
    just a question about my 04 rxp with low mph of 66.7?
    mods are: works grate , 14/19 , green sc ,
    RE b/o , thru-hull , free mods, rest is stock?
    why would my mph be low or is that right?
    oh had full tank also and my weight is 115kg....
    (8050) rpm

    thanks in advance

    IF you're turning 8050 it couldn't be slipping too much. Just take off the SC outlet hose and see if you can turn it with your fingers... Ron
