[C38] three blade fixed propeller

[Charles Finn]

The Mighty Quinn makes 5.5 kts at 2400 rpm with a two blade fixed prop 
(by both of my GPS gadgets).  My old Signet guages regularly told me 
something higher and my Navman units calibrated out of the box agree 
with my GPS.  BTW, the bottom paint was new last year and I am in fresh 
water with almost no bottom growth. 
I am thinking of going to a 3 blade prop because I have heard it will 
reduce "prop walk."  Is that true?

Thanks,
Charles Finn
