Propeller Replacement; Removal - Mercury 15 EFI FourStroke Service Manual

Propeller Replacement

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.

Removal

1. Remove the spark plug leads to prevent the engine from starting.
2. Shift the outboard into neutral (N).
3. Straighten the cotter pin and pull it out using a pair of pliers.
4. Place a block of wood between the gearcase and the propeller to prevent rotation, and remove the propeller nut.
5. Pull the propeller straight off the shaft.

IMPORTANT: To prevent the propeller hub from corroding and seizing to the propeller shaft (especially in saltwater),
always apply the recommended lubricant to the entire propeller shaft at the recommended maintenance intervals and also
each time the propeller is removed.
