If you want the boat to run at optimum performance thru out the entire
operating range - go w/ a good 4 blade SS for your application. You won't
believe the difference.

I've been talking to a prop shop about changing from a 14.5 X 19 X 3 alum.
to a 4 blade SS prop. The shop recommended a 14.5 X 17 X 4 but said that I
would loose 3-5 mph from the top end, I guess because of the drag of 4
blades. Is there any other size 4 blade that won't cut the top speed?

TIA
