IMPORTANT: This document guides our dealers, boatbuilders, and company service personnel in the proper installation or
service of our products. If you have not been trained in the recommended servicing or installation procedures for these or similar
Mercury Marine products, have the work performed by an authorized Mercury Marine dealer technician. Improper installation or
servicing of the Mercury product could result in damage to the product or personal injury to those installing or operating the
product.

NOTE:

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.

After completing installation, place these instructions with the product for the owner's future use.
