Alpha Propeller Removal

Rotating propellers can cause serious injury or death. Never operate the boat out of the water with a propeller installed. Before
installing or removing a propeller, place the drive unit in neutral and engage the lanyard stop switch to prevent the engine from
starting. Place a block of wood between the propeller blade and the anti‑ventilation plate.
1. Place wood block between propeller blade and anti‑ventilation plate to prevent rotation. Straighten bent tabs on tab washer.
2. Turn propeller shaft nut counterclockwise to remove nut.
3. Slide tab washer, drive sleeve, propeller and thrust hub off propeller shaft.

Alpha Propeller Installation

Operating the engine with a loose propeller can damage the propeller, the drive, or drive components. Always tighten the
propeller nut or nuts to specification and check for tightness periodically and at the required maintenance interval.
