There is
It will be said to join as a premium member, where you can download a manual that details how to. There is an 07 RXP manual here, the one I downloaded, and it will do you wonders. Washers run 70-100 $ a set, you can buy a toolset w/washers for about 120.00 on line. BRP recommends a SC rebuild every 100 hours, funny my 07 manual states every 200. The skis are more prone to failure because they load/unload more often stressing the SC. The total rebuild kit with washers is 300+- dollars. There is a site on the net, this gentleman will replace washers for 50$ labor or rebuild for 75$ labor, you pay parts and shipping. My local SEADOO dealer quoted me 300.00 for a rebuild kit ( good price ) and 350.00 in labor (yikes) I can order a new SC delivered for 650.00 and install myself. There are a lot of rebuild threads out there, not too hard if you feel you are up to the task.
