7.3.1 Propellers check and maintenance

Check the edge of the propeller frequently for dents or damage.
If deep dents, cracks or tears are noticed, they must be replaced or repaired.
Mineral deposits on the propellers can be caused by a malfunctioning or missing cathodic protection system.
Remove mineral deposits on the propellers with household cleaners suitable for dissolving limescale and deposits.

DANGER

Checking, cleaning and maintenance of the propellers must only be carried out with the engine stopped and prevented from being started.
