    Unofficial poll on pumps - mod for double bearing or stock?

    I know in the past, many of us with modded RXPs had our pumps modded by Skat too, either triple or double bearing mod. I was curious if most people with 80+ mph skis are still going double or triple bearing mod and oil in the pump, or if many stay with stock setup?

    Did a search on part numbers, these bearings are also used on GM cars and toyota cars.
    I rebuilt my pump and I cleaned the grease off the new bearings and went with full synthetic oil.
    I think grease squeezes out, and doesnt lubricate as good a gear oil.

    The double or triple bearing mod will result in less pump shaft flex, which will keep the impeller centered in the housing and keep it from flexing and eating into the wear ring...important if you run the ss ring. Skat does not do the triple bearing mod any more. The triple bearings, although more stable, dropped rpm's by 100 or so due to the extra drag of the third bearing. The current double bearing and seal setup is far superior to the original design by Skat. I'd be interested to know if the Rotax racing 16 vein pumps use double or triple bearings...any one know for sure?
