Thread: XLT1200 Cavitation

Hi guys another quick question. Been told I may need a pump seal kit and that Moulded inserts fill the voids in the OEM pump shoe also limiting cavitation. Is this a big job? My ski bogs and cavitates a bit when pulling out of the hole when trying to pull up a single person on kneeboard. Once up and going its fine just useless down low. Also does the standard XLT have pump seals? Or is the aftermarket kit there as a result of design flaw from factory by Yamaha?

im intrsted in this as well as mine does it when theres alot of weight on the back end and cant weigh the intake into the water enough

Ive sent an Email to Steve ans PWC Performance OZ, WHen i get a reply I'll be sure to post any info gained thanks

Hi Brentle,

Yes you'll need a seal kit. Steve will help you with this.

I installed one in my GP1300R apart of the Riva stage 1 kit and problem gone. My jet ski can pull me out of the water now on one ski!!

Good luck
