3 blade SKAT vs. 4 blade SOLAS
in a stock RXP which one would perform how??
any reason to choose one over the other??

I say 4 blade for sure on stock. Just what i prefer.
IMO, to get a 3 blade perform you need some HP.
3 blade is a dog on top without alot of ponnies.

I think ı'm going to buy 4 impeller skat trak. and ı remember that my ski never cavitates. so should ı buy 4 impellers? because you asked me something about cavitation and ı remembered, ıt don't cavitates.

13/18 3 blade for stock setup works very well.
But both the 13/18 3 blade & 14/19 4 blade needs an air intake & riva grate to get some better #'s.
4 blade will be faster on top but the 3 blade will get you there faster before it tops out.

jetlover, remember some of these guys are talkin about impellers for the bigger engine RXP215 and RXPX255. you have to make sure you get the impeller pitch for a RXP155.
MRRACING, are you sure that 10/21 is for a rxp155?? i checked the charts at SkatTrak and i think the 10/21 is a 4 blade for the larger diameter (215 housing) and the bigger engine. and it would also then not mate up with the 155's shaft...
just double checking.

cavitation has nothing to do with 3 blades or 4 blades. it has to do with the wear ring and impeller, if they are damaged or not. when you buy an impeller , get a new wear ring at the same time.
