Pump Shoe Fins on RXP - What do they do?
I was wondering if anyone knew what the purpose it of the fins inside the pump shoe?
I have a 2005 RXP that these were mostly sheered of (Rocks I suppose) what affect will this have on the ski?

Broken fins will cause cavitation. Grind them all off and you will be fine... Ron

Some say its good to direct/stabilize water coming in.....so its not as turbulent.

All the reading I've done is if you have a broken one grind them all... if not just leave them unless you're really bored... !
