Mark, the standard prop from Whitby was 13x7 with 7/8" shaft 2-blade with
an Atomic 4 engine. If the engine has been changed, the prop would also be
changed. Also, if you have a 3-blade prop you could us a smaller diameter,
higher pitch prop. The is also a 3-blade smaller diameter prop that was
specifically designed to the Atomic 4 and several people switched to that
prop. The distinguishing feature of that prop is the tips are bent in
slightly, like the singlets on a 737 aircraft. Send me a picture of your
prop and let us know what engine you have. The lost does not accept
pictures so reply to me with it.

Had my boat hauled yesterday and was surprised at how small the propeller
was, about 8 or 9 inches in diameter.
