Propeller Removal and Installation

Caution: Before you start, ensure the fuel is disconnected and there is no live electrical circuit to your outboard prior to working on the propeller. Remove ignition keys and kill switch/lanyard.

Step 1: Block the propeller with a block of wood, to prevent the propeller from spinning as you apply pressure to the prop nut.
Step 2: Straighten and remove the cotter pin, using a pair of pliers (some propellers will have a circular tab, instead of a cotter pin).

Step 3: Remove the propeller nut with a ratchet, or a prop-puller (a wrench designed just for prop nuts).
Step 4: Slide off all washers and spacers.

Remember: keep these in order, and lined up so you know what goes back where and in which direction.

Step 5: Slide off the prop itself.
Step 6: Before you put on the new propeller, degrease and clean the spline. Recoat with grease.

Putting on the new propeller is simply a matter of following the above steps in reverse.
