CAUTION: Before servicing a propeller, be sure the engine is in neutral with the ignition off or disconnected to avoid any possibility of the engine starting and causing injury.

CAUTION: Do not install any propeller without a thrust washer in place. If a thrust washer is not used, severe damage could occur to the propeller and/or engine. If you see a tapered surface toward the engine end of the prop shaft, the thrust washer is not in place on the shaft. Your thrust washer may adhere to the front of your old prop when removed.

Mercury/Mariner/MerCruiser: If the propeller strikes the Trim Tab, replace the trim tab with Quicksilver flat plate anode #76214A5 or equivalent available by calling toll free (844) 273-2993.

Make sure your thrust washer is on the prop shaft with the tapered end in first to match the tapered surface of the prop shaft.
Caution: Do not install any propeller without the thrust washer in place.
Clean and grease the splines of the prop shaft.

Align the keyways in the propeller housing with keys on the hub. Slide the propeller housing onto the hub.

Slide the propeller and hub assembly onto the propeller shaft. Place your tab washer on the end, then install and tighten the locking prop nut. Make sure your tab washer and prop nut turn simultaneously. Tighten to 55 ft-lb. Align 3 tabs on tab washer with grooves on castellated Spider Washer cap. Tap or bend tabs down into grooves.
For propeller shafts that use a cotter pin: Install the Locking Nut and tighten to 55 ft.-lb. Reinstall Cotter Pin and bend ends or consult your Engine Owner’s Manual for proper prop nut torque and fit specifications.

Rotate Prop in neutral by hand to make sure the blades do not strike the trim tab and anti- ventilation plate.

NOTE: Locking Nut should be checked for tightness every 20 hours of operation.
