IMPORTANT: Check the tightness of both propellers after 20 hours of operation. Tighten the propeller nuts if necessary. Do not operate the vessel with a loose propeller.

Propeller Inspection and Maintenance

Inspect the leading edge of the propeller frequently for nicks, gouges, and damage.

Propellers with large, deep dents, gouges, or torn metal should be replaced or repaired.

Mineral deposits on stainless steel propellers can be caused by an inoperative or missing MerCathode system.

NOTE: Mineral deposits can be removed with household cleaners such as vinegar or other cleaners that remove lime and mineral deposits.
