Propeller Installation

Some propeller installations may require the use of special OEM mounting hardware not included with this propeller. Use only

hardware specified by the engine OEM. Special trim tab or anodic plate may need to be purchased separately for propeller

clearance. Use the original propeller hardware or order replacements for worn or damaged parts.



Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or death

due to fire, explosion, electrical shock, or unexpected engine starting. Always disconnect the battery cables from the battery

before maintaining, servicing, installing, or removing engine or drive components.



Rotating the propeller shaft may cause the engine to crank over and start. To prevent this type of accidental engine starting

and possible serious injury caused from being struck by a rotating propeller, always turn the ignition key or lanyard stop switch

to the "OFF" position and remove the spark plug leads from the spark plugs while servicing.

1. Disconnect all of the battery leads from the battery.
2. Remove the spark plug leads and ground them to the engine block.
3. Lubricate the propeller shaft splines with one of the following lubricants.
