    65u GPR conversion

    Donor Motor:
    65u
    OEM Pistons
    OEM head milled to 145psi
    Ported
    Trued/welded Crank

    Hull:
    2000 Yamaha GP1200r purchased with everything but tank and motor for $575 including Continental trailer

    let the pictures begin:
    reason i had to swap my engine out of my old hull:


    Engine Build:








    GPR hull at auction:



    After a good wash:


    Polishing the bottom:



    After countless hours of pressure cleaning, sanding and painting engine bay:



    After removing all stickers and wet sanding/polishing:


    Engine and all components installed:


    parts used:
    GPR fuel tank
    GP1200 65u engine and CDI
    stainless midshaft from gp1200
    pump shaft from GP1300R
    GP1200 Gauges

    the most complicated part was moving the forward engine mounts backwards in order for the motor to bolt on correctly. Let me know what you guys think! ill post more pics soon!

    Thanks i just went for its first run. Its awesome compared to the old hull the engine was in no more porpoising! However i do have to get a new impeller because when i accelerate it all the way from idle it hits the rev limiter for a couple of secs and then goes. Im thinking a solas 13/19?

    Sure, get the TT commercial because it will hold max rpm and has hour meter.
