    alignment

    is it always necessary to do a alignment when ever the motor is removed.i have had the motor out of my txi and yami suv and never did anything like that.

    Necessary? No, the motor will still spin the driveshaft which will turn the impeller and make the ski go. However, a bad alignment will cause premature wear on the splines where the drive shaft and coupler mesh leading to failure....

    BFC is correct of course. My experience... if you have a good alignment to start with and you remove the engine (keeping all shims where they are)... and then put the same engine back into the same ski. Your alignment will still be fine. (unless you somehow cock off the engine on the mounts weird) The engine should sit right back where it was and everything should be back in alignment.

    If you put in a different engine or change the engine bedplate or engine mounts or remove the jet-pump base... then yes, you should really do a re-alignment.

    Cheers!

    If the driveshaft is binding in the coupler splines then it is way out of alignment.

    If it is mis-aligned but not quite binding there will still be wear in the spline area as the coupler and shaft rotate.

    If you only need it this once... more affordable to rent one. But if you see long term use and or other Polaris pwc in your future... they are a handy tool to own.

    You can rent the Polaris alignment tool from John a Watcon. Or buy one from him too, I believe.

    I've also worked with a new maker of these alignment tools who sells them on ebay. Aftering helping him exact the specs on the rod... his product he's making now is good. See this thread:
