    Different Impellers?

    I just noticed that the stock impeller is different from year to year on my ski:

    2000 SLX Polaris 5132202
    2001 SLX Polaris 5132707
    2004 MSX140 Polaris 5132707

    2000 SLX Nu-Jet PL-A 7.0

    I'm currently running a NuJet in my SLX, but I belive the stock impeller was just a NuJet to begin with...

    Does anyone have any thoughts on whether a 2001 SLX prop would perform better on top than a 2000SLX/NuJet 7.0 in my ski?

    EDIT: What's driving this is I see a 5132707 on FleaBay and was thinking of buying it as a spare for my MSX and the SLX, but it's not the same as my current 7.0, so I wondered if it would be an improvement or not......

    It's no wonder you are running into this as there are a few things going on here. Keep in mind NuJet does make the stock impellers for Polaris but NuJet also makes impellers for their own retail sales. Due to proprietary reasons, the impellers NuJet sells for retail cannot be exactly the same as the Polaris impellers. There are 4 basic impellers out there for your watercraft...however there are a few trial versions out there that people have possession of. Anyway, in 2000 Polaris had the 5132202 which is similar to the NuJet 7.0...there are slight differences between the two but net results are the same. Then Polaris came out in 2001 with the 5132707 which general gives better out of the hole...less spin out. The newer NuJet 7.0 impellers were changed to reflect that of the 5132707 impeller. The main difference between the 202 & 707 impellers is the blade length/overlap and the position of where the blade starts...closer to the top. I personal like the newer version that you buy from NuJet because they use a solid hub where the Polaris impeller is more hollowed out. As for top end, I haven't really noticed much difference between the two when used at the designed rpm. The 707 on the slx might be a tad slower top end like 1mph or so because it was really designed for the MSX which uses a higher top end rpm.

    What changes to the newer design can improve launching, and further reduce the cavitation and spin?

    props

    i ran all 3 back to back on the virage before and after pipes.the 707 was 2 mph slower but was much better from a takeoff.after working the 202 and 7.0 the takeoff is even with more mid and top pull.but i'm concerned with the bigger carbs the 202 won't stay hooked on either ski.its allright tho,got a 17/24 and 8 vane for the pro and a 17/22 for the virage,that'll hookem up

    I'm sorry, can you clarify? The 707 was slower, but a better bottom end hit; but you were able to improve the 202 to even better than a 707 after it was worked? Is that correct? So you recommend a 202 tweaked? And by whom?

    close

    almost correct.the 202 and nu-jet 7.0 would hook up much better after tweaking,as good as the 707??close or even.the 202 and 7.0 were faster in terms of max mph and seemed to pull a little harder from the top of the midrange up.for an slx with stock carbs the 202 or 7.0 is a great prop.the msx with fi hits harder from a takeoff with more weight to move,thus the 707.the 01 pro 1200 benifits 2 ways from the 707.its a better handling ski and is a funner ski with the improved takeoff and with the triple pipes and their added hp needs the better hookup.the virage went back to a skat prop in 01 and 02.go figure.i'd like to have another 707 for river runs on the pro with a 6 vane.it has crazy hookup with the 8 vane and prop so much anything over a 3 wedge and you WON'T keep the nose down on takeoff,thats why its getting the trim tabs

    second that...202 for the slx and 707 for the MSX. If looking for a spare for either then the 707 is worth it. It can be easily modified to get back the top end for the slx. Either impeller can be modified to get you what you want, it's just that depending on what you want, one or the other would just be a better starting point...less mod required.

    Thanks for the input! Turns out it's not a spare, it's going straight into service; I finally got around to pulling the pump on the MSX in my 20F freezing garage today, wow! .020" clearance, tons of dings, etc. I'm amazed at how rough the impeller was, considering the hull is in such nice shape.... The hull looked so good I didn't bother checking the impeller before I bought the ski!

    The interesting part of the impeller I bought?

    You'd be surprised how bad an impeller can be beat up. I never ride in shallow water and had a HUGE ding on one of my blades.

    Delegem, you don't have a torpedo heater? Makes winter work tolerable.

    FOR MY WARM WEATHER FRIENDS: a torpedo heater is a long cylinderical shaped device that puts out large amounts of heat (30k-150k BTU) to warm up a surrounding area. Often using K1 (kerosene) or propane.
