    Congrats! And the fun begins....... Start reading!!! http://polarispwcknowledge.shorturl.com/ There is alot to do before you start talking about performance upgrades (or you could just look at my signature below for some of the common upgrades). This is very important stuff, so dig in!

    Look into the fuel system update information as a good starting point.....

    Post pics during your adventures and please ask lots of questions!

    The Stock 035 prop is pretty good on those. The best performance gain can be had by making sure the jet pump is in perfect condition. Good wear ring and good clean prop and stator with no nicks or dings. Impeller clearance .008 or less is ideal. The tighter that impeller is in the wear ring, the better your overall performance will be. I would try a skat 12/17 on that ski. I tested a 13/18 skat on one of those and it was too much prop for the 750. Get a 6 vane stainless stator. Aftermarket reeds and spacers help on the Fuji motors too. I really liked what the Boyesen pro series reeds did to my 650. Get a GPS top speed and note peak RPM to get a baseline to start with.

    I have run the Polaris 035 and 079 on it. They are both similar with a little more top end on the 079.

    BryanP has some good recommendations on aftermarket....

    Oops I misread. I thought you had a SLT 750. Seems like everyone else has one of those. On the SL the Skat 13/18 might be good. I have one I will try on my SL 750 one of these days and report back.

    Why does the AAT always get left out? Everyone I've seen who owns one has said it is a very impressive and cost effective mod...

    The real question is, what should you do to optimize your ski for the water conditions you'll NORMALLY be riding on.

    It makes no sense trying to make it go faster if the water won't let you reach top speed.
