Checking Propeller
Before inspecting, removing or installing the propeller, always take actions to ensure the engine will not
accidentally starts, such as removing the spark plug caps from the spark plugs, placing the shift control in
neutral, and removing the lanyard from the engine stop switch, etc. Serious accident could occur if the
engine starts when you are nearby. Do not use your hand to hold the propeller when loosening or
tightening the propeller nut. Put a wood block between the anti-cavitation plate and the propeller to
prevent the propeller from turning.
1. Check each of the propeller blades for wear, erosion from cavitation or ventilation, or other damage.
2. Check the propeller shaft for damage.
3. Check the splines/shear pin for wear or damage.
4. Check for fish line tangled around the propeller shaft.
5. Check for the propeller shaft oil seal for damage.
Removing the Propeller
1. Straighten the cotter pin and pull it out using a pair of pliers.
2. Remove the propeller nut, washer, and spacer (if equipped).
3. Remove the propeller and thrust washer.
Installing the Propeller
Be sure to install the thrust washer before instating the propeller, otherwise the lower case and propeller
boss could be damaged.
Be sure to use a new cotter pin and bend the ends over securely. Otherwise the propeller could come off
during operation and be lost.
1. Apply a marine grease or corrosion resistant grease to the propeller shaft.
2. Install the spacer (if equipped), thrust washer, and propeller on the propeller shaft.
3. Install the spacer (if equipped) and the washer.
4. Tighten the propeller nut. Align the propeller nut with the propeller shaft hole. Insert a new cotter pin in
the hole and bend the cotter pin ends.
