[alberg30] Diesel Prop Size/Pitch

[Bob Lincoln]

I suggest you contact Scott Stewart at Proper Pitch in Delaware.  They have
a web site and you can contact Scott at stew at shore.intercom.net.  The
selection of a suitable prop is somewhat an art, but many factors are
needed, including displacement, reduction ratio, horsepower, desired speed
and shaft rpms.  I think that while a 13 inch diameter two-blade is about
the largest you can fit into the A30 aperture, the top and bottom clearance
are too small to be the optimum.  See the tables in Skene or Calder for a
start.  The props suitable for the Atomic 4 are not recommended for a
slower-turning diesel.
