Hi,

Moving along with the Engine Project for Far Cove...

Decided on a fixed 3-blade Campbell Sailor for the new engine (actually my
finances decided for me!). But what size?

Robert at Atomic Engine Service (where I'm buying the engine and prop)
recommends 14x8 (grudgingly 14x9).

VicProp (Main dealer for Campbell Sailor props) recommends 14x12.

gpcprop.com (generic prop-sizing) recommends 15x10.

Catalina recommends 14x9 for the ORIGINAL M25 (21hp compared to 26hp for the new
one)

Bob McCulluch of TechNotes, Mainsheel Magazine (highly respected, apparently
knows more about the Mk I than Catalina!) recommended a 15x10 for the ORIGINAL
M25.

I think 14in is a good diameter - I'm concerned that a bigger prop means more
drag. I'm leaning towards 14x10 but...??
