Maintenance: S drive and reverse gear
Corrosion protection. Check
Check the sacrificial anode () on the drive and the
three sacrificial anodes () on the propeller. Replace
with a new anode if 50% of the material has perished
or at least once per season.
IMPORTANT! Use zinc sacrificial anodes for
salt water and magnesium anodes for freshwa-
ter.
Remedy any paintwork damage on the drive ac-
cording to the instruction in the chapter: Laying up /
Launching.
Replacing sacrificial anodes
. Remove the propeller (see the next section).
. Remove the sacrificial anodes. Thoroughly scrape
clean the mating surfaces on the drive and pro-
peller.
3. Apply thread sealant to the screws for the sacrifi-
cial anodes on the propeller.
4. Install the new sacrificial anodes. Tighten the ano-
des so that there is a good metal contact.
5. Reinstall the propeller.
The sacrificial anodes oxidise when they come into
contact with air. This reduces the galvanic protection.
There may even be oxidisation on the surface of a
completely new anode.
Always clean the sacrificial
anodes before launching the boat.
IMPORTANT! Use emery paper. Do not steel
tools when cleaning, as these may damage the
galvanic protection.
Folding propeller. Cleaning
The propeller must be cleaned and lubricated once a
year. Remove the propeller and clean all components
thoroughly. Apply waterproof grease to the propeller
blade teeth and bearing surfaces so that the propel-
ler folds easily. Also apply waterproof grease to the
studs, spacing sleeve (drive), propeller shaft and hub.
WARNING! Prevent accidental starting. Remove
the ignition key and turn off the power at the
main switch before working on the propeller.
