    So far the yamaha pump with the big prop has been the fastest and has been keeping the revs where its safe for the long distance race .. i will be testing a seadoo 15/21 tweeked to a 23 on friday. Apparently there is going to be some real fast conversion skis racing the next one ... so i need to lift my game ...

    Took the ski out ... was windy as shit .... mainly choppy but a few smoother spots here and there ... i couldnt hold in on long enough to get a true speed reading ... i was running 17psi according to dashpac 83mm nozzle started with a full tank and i used 2 bars ...first up was HO pump with ar230 prop . 8560rpm and 85mph .
    Then i fitted the seadoo pump with a 15/23 prop pitched by me . L13 cone with all the washers plus an extra 4mm .8860 at 90mph ... i may have got a bit better water with the seadoo pump .. but still crappy water ... ho pump hit the rev limiter 5 times .. seadoo 2 times ... the seadoo pump felt like it pulled harder all the way through the rev range ...

I will epoxy up the Yamaha mounting holes and the syphon hose hole .
    some have asked about the Yamaha nozzle on a seadoo pump ....

    this is the adapter that I got off a member of this forum . that fits Yamaha nozzles to the seadoo pump .. you need to drill out the Yamaha nozzle to seadoo bolt Patten ...

    So what's your reason for trying this Steve
    Is just for the lucky 13 cone
    Or just because you can't sit still
