[C38] three blade fixed propeller

[Jim and Barbara]

Chapman's has a good discussion of prop walk.  Primary cause is the angled
shaft; I'm not sure that the prop makes much difference.  Our boat makes 6+
knots at 2000 rpm with a 2-blade folding prop.

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
