    2002 gtx 4 tec limited jet pump

    I have a 2002 gtx 4 tec, the bearings in the jet pump went and took out all the internals in the housing with it. It seems it's impossible to get a replacement housing for this year. Does anyone have any info on what other years i can look for that would fit. Thank you.

    If I don remember bad you can use a 03 o newer jet pump and have to replace driveshaft as well

    I believe I have a good '02 housing here that needs rebuilt. What's the part number on yours? 10 vane?

    the only new pump housings available require a new driveshaft and pto seal. Makes it pretty expensive to repair a 19 year old ski.

    I'd jump on any serviceable housing from that year as they are getting harder and harder to come by

    you can find out more by doing a search of the forum, this issue has come up quite a few times, and everybody had a first time encountering the "oops no jetpump housing available" issue, including me!

    Well the good news is that the money is already spent. I already replaced the driveshaft with a wsm replacement. It states it's for a 02-04 and since I did that I already changed the pto seal and carbon seal. The skis sat for over 4 years. I could not get the top off to move to expose the clip so I had to cut the hat off.

    I'll check tomorrow. I was actually keeping it around for a 951 project......poor man's Skat pump. But I'm willing to help another enthusiast out.

    Decided to just run out and check it out. Good pump, nice vanes, cone, good shaft, and some bearing parts. Wear ring (of course) is shot. Might have a new wear ring in stock I could pop in......what's it worth to you?
