A SS Prop. will only increase your top speed 3 or 4 miles an hour. Your hole shot will be better. But at $300.00 to $ 500.00 for a SS Prop is The ??? You might change the pitch lower for higher top end. higher pitch for better hole shot. Your 21 should be good enough for sking. check out Ace Propellers.com for Props.
