If the jam nut and prop nut are installed properly,
the propeller should not loosen. If you tighten both
nuts holding only the propeller blade, the nuts
could possibly thread back on the shaft to the
cotter pin. It is important that the above procedure
be followed.
NOTICE
2. Install the propeller on the shaft without the
key in the keyway. Slide the propeller all the
way on the shaft until it seats. Mark the shaft
on the leading edge of the hub with a felt tip
marker and remove the propeller.
3. Install the key in the keyway and slide the
propeller on the shaft. If the key is not
pinned, tap the key back slightly as the
propeller slides up the taper. This will
ensure that the propeller does not ride the
key up the keyway end radius, thus forcing
the propeller off-center. The propeller is
properly seated if the hub is in the same
position as previously marked.
4. Install a board (2 x 4) against the hub
perpendicular to the keel and rotate the propeller
clockwise until one blade rotates against the
board. Do not put a board between the strut
and the rudder.
5. Install the large bronze prop nut on the propeller
shaft and seat the propeller with the correct
torque (see table, next column).
6. Install the jam nut and torque to 100 ft. lbs.
7. Install the cotter pin.
