    2005 PUMP CONVERSION PARTS LIST.

    If you are considering converting to the 05 pump "combo" here is the Parts list with part numbers for a "complete" shaft/stator/bearings/seals/85 mm reduction nozzle/pump cone assembly.
    You can save money by using your current driveshaft. I chose to order a new one.

    This list does not include the 2" extension. I did not need the 2" extension on my 2000 GPR.

    The driveshaft on the 2005 GPR is the same as the 2000-2001-2003-2004
    2002 uses a different Driveshaft.

    The list does not include the dyna-fly impeller.
    You know where to go for that :P

    These part numbers are from www.boats.net

    I did not list prices for due respect.

    Excellent Post.

    Here is the 2" extension post. Watch for duplication of part numbers.

    Can you elaborate on the 2002 driveshaft? If I don't plan to do the 2" extension, do I still need a different driveshaft for my '02? What's the difference in the '02 shaft, anyway?

    So,
    The 2002 year is the ONLY year with a shorter driveshaft.

    Why? Who the hell knows!

    Yamaha introduced the intermeddiate shaft that is now used on the 2003 and up on your ski. Consider it a blessing in disguise...you don't have to pull your engine forward to do a 2" extension upgrade.

    So here are YOUR options:
    1. 2" extension only: Buy all the parts, and replace your driveshaft.
    2. 2005 pump upgrade only: Buy all the parts and use same driveshaft.
    3. Do both: which will include replacing the driveshaft.

    In short, if you are NOT doing the 2" extention for THE 2002 MODEL GPR ONLY, then you don't need a new driveshaft. If you do the extension upgrade, you are one step ahead of the game.

    The biggest hassle in doing the 2" extention, is that the GP1200R rideplate will not fit without major grinding. You must releave the rear of the rideplate, where it touches the 2" extension, as well as the area around the base of the nozzle. There are pics on the 2" extension thread and on my webpage.

    So what is the best way to move the engine forward to change the 2 inch shaft? Does the entire pipe need to go? Motor mounts?

    Does anyone have pics?

    Thanks and Happy Holidays!

    dont move the engine forward an worry about the shims. take the support out that the electrical box bolts to. right in front of the battery. unbolt it from the hull and cut away the glue.

    We put the 05 pump on BDNJ's ski today. Its a plug & play install. He has the IR plate and no grinding of the plate or pump was necessary. Brendan got the 05 pump kit from Carl at Island Racing.

    SMW,
    We were looking at this tonight. Honestly, I'm a little wary of ungluing the stringer plate, and then getting the engine to line back up afterwards.

    Has anyone inspected the alignment AFTER disturbing the stringer plate?
