1.7.6. Lubrication
The engine is lubricated according to the specifications in the operating instructions of the engine
and other installations.
Please note that during oil change the oil must be sucked out with a pump. When changing the
filter you should use an oil absorbing cloth against dirt.
The oil must be changed at least once a year even if the boat has used very little.
A well maintained boat should never leak. All the same, the engine’s mount is shaped in the form
of an oil sump, so that not even the smallest amount of oil can enter the bilge and thus the
pumped out bilge water. In case water that is possibly mixed with traces of oil collects there, it
must be filled into a separate canister by means of a small draining pump and disposed of
together with the used oil.
1.7.7. Gearing
The gearing is a mechanical gearing. With it can be changed the running direction. It is mounted
directly onto the engine. Please read the special operating guide and the maintenance
instructions of the gearing.
The gear was designed in order to withstand the stress during normal service. Avoid abrupt
switching processes.
1.7.8. Gear shift
The engine’s speed and the gearing are controlled via mechanical gear shifting with bowden
wires. (see 1.7.7).
1.7.9. Sail drive
The sailing yacht has a sail drive. The output of the drive is similar to a Z-drive transmitted to the
propeller, but the difference is the propeller is under the yacht. The lead through at the bottom is
sealed.
Also check the tightness of the sail drive during your inspections. 
Avoid contact with the seabed because this could damage the
propeller or the sail drive. 
Check all underwater components of the shafting when preparing
for winter storage and remove mussels and other marine foulings
from the bearings. 
Pay attention to flotsam in the water. Lines and plastic bags which
come into the bearing can damage the bearing and the shaft and
reduce the life time. 
