[C320-list] DO NOT READ IF YOU ARE TOO BUSY.Was: Regatta Tech Sessions - a summary NOW: AutoProp Speed Warning

[Bruce Heyman]

There is a blue warning label on the outside of the envelope that my
Autoprop installation instructions came in.  It tells you to make sure the
engine is engaged into the ahead position when sailing to allow the
Autoprop's blades to feather.  However, "...WHEN EXCEEDING 13 KNOTS UNDER
SAIL LEAVE GEAR SHIFT IN NEUTRAL...."  I'm thinking of having a warning
label made up for my binnacle to remind us to move the transmission to
neutral when we chose to sail over 13 knots....:-)

So there are 3 conclusions here. First, the engine should be able to turn 
3600 RPM at hull speed regardless of which prop is used. Second, 2800 RPM is

a good cruising speed assuming the prop is pitched correctly. Third, 
Autoprops are not pitched correctly and are not adjustable.
