WARNING

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. Shift the outboard to the neutral ("N") position.

for removing spark plug leads.

2. Remove the spark plug leads to prevent the engine from

starting.
