[C320-list] Folding Propellers for 3YM-30

[Bob & Bel Harrison]

Maverick (#1007) has a 15" 3-blade "Classic" MaxProp.  It required the prop
shaft to be shortened maybe 1/2" for installation.  With the adjustable
pitch set to 20 degrees (10.3 inches), we get a bit less than half a knot
more speed for the same engine revs than a 15x9 3-bladed fixed prop, and I
feel it could take a bit higher pitch as the engine has no trouble reaching
high revs. Under sail, performance is much harder to quantify, but we're
pleased with it.

Can any of the owners with the new 3YM-30 engine tell me what type, size and
pitch of folding propellers they installed and how they like them?  Also any
modifications of equipment necessary to install?
