[C320-list] Folding propellers--Size/Gori 2-blade

[belairlk at aim.com]

After reading everyone's comments and experience: members who first tried Gori 3-blade size 16-1/2 x11 reported cavitation, etc., and switched to Gori 3-blade size 15 x 10 which they say works well on the 320.
 
The Gori 2-blade size for 320s brought differing opinions.  Some members report 16-1/2 x 11 has been terrific with Yanmar 3GM30F.  Some members report 15 x 10 works well with Perkins engine.  Some members feel the 2-blade size Gori recommends for above Yanmar, 16-1/2 x 11, would be too large and/or have too much pitch.  (Gori now recommends 3-blade size 15 x 11).
 
My feeling is to try the Gori 2-blade 16-1/2 by 11.  Especially since Steve, Alchemist #909, has it installed for quite awhile, says he reaches hull speed @ 2,800 rpm, runs great with it, and no problems.
