8.5.2 Periodic checks on propellers
It is advisable to carry out this operation with yacht in a dry shore because
maintenance is in this way eased. Check that the propeller paddles do not
show notches or breaks, scales or barnacles, which may have a negative
influence on the yacht output while sailing. If you find traces of corrosion,
you must check the condition of the anodes and with heavy irregularities
replace the propeller.

DANGER
To clean and check the yacht in water: disable the engine and
generator start.
S
CAUTION
Ensure that the engines cannot be started before you carry out any
propeller or shaft cleaning or checks with the yacht in the water.
Remove the keys from the ignition. If an engine is started when a diver
is underwater, serious injury or death could result.
NOTICES
Propellers are not interchangeable with each other. Each yacht model
has its own propellers. Check to ensure that replacement propellers
meet the specifications of your yacht. Do not replace the propellers of
your yacht with others of unknown or doubtful origin. Contact the
BERTRAM Customer Support for more details.
