[C320-list] Folding props

Thu Jan 5 05:16:40 PST 2006

Went out to the Alchemist last night (raining and 39 deg.) and checked
my Gori 2 blade folding prop.  It is a 16.5" diameter prop, but I
couldn't tell the pitch.  I rooted around through my papers and found
the original order, and it is a 16.5 x 11.  That is what Gori
recommended.

This prop works great under the Alchemist (#909) with the European
Yanmar 3GM30F, achieving hull speed at about 2800 RPM (possibly a
little less), with no excess vibration due to the prop tip being too
close to the hull.  This is probably because the tip of the prop is
further back (about 4 inches) than a fixed prop would be, thereby
giving sufficient clearance.
