CXO300 OWNER’S MANUAL
6 Fit the propeller. Check that the forward bore of the propeller is inside the transmission and that
the radial gap is minimal. A gap may result in exhaust gases ventilating the propeller leading to a
significant loss of thrust. If in doubt, contact your Cox Powertrain official dealer for assistance.
7 Fit any washers and the propeller nut retaining ring, if used. Ensure the order and orientation of
fitment is correct in accordance with the hub supplier’s guidelines.
8 Hand start the propeller nut on the propeller shaft thread and turn by hand until seated against
the retaining ring.
 CAUTION
Tightness in the movement of the retaining nut over the propeller shaft thread may indicate thread
damage and increased risk of loosening during operation. Contact your Cox Powertrain official
dealer if in doubt.
9 Hold a block of wood between the underside of the anti-ventilation plate and propeller to stop the
propeller from turning clockwise. Tighten the propeller retaining nut, then remove the wood block.
 NOTE
Tighten the propeller nut to 135 Nm (100 lb-ft).
10 Following the hub supplier’s guidelines, bend the tabs on the retaining ring over the nut, if used.
11 Visually inspect the propeller and hub parts for correct seating. With protective gloves on, turn
the propeller over and check for smooth movement.
