PROPELLER MAINTENANCE

Propeller damage is caused by striking solid objects. If the propeller is not rotating at the time it strikes a solid object, the damage is usually confined to just one blade and may be diffcult to see. If the propeller is rotating when it strikes an object, usually the resulting damage can easily be seen on all blades. 

CHECKING/REPAIRING PROPELLERS 

Step 1 

Ensure the engine is OFF and the emergency safety stop switch is disconnected. 

Step 2 

Clamp a small rule scale to the shaft strut, parallel to the shaft so that the end of the scale is 3/32-inches from the leading edge of a propeller blade.

Step 3 

Rotate the propeller slowly. There should be no more than 3/32- inch variance between the blades. If the propeller is damaged, see an authorized MasterCraft dealer for repair or replacement as necessary.
