Technical data

2. OPERATING TEMPERATURE
The maximum permissible temperature of the transmission oil is 130'C. If this temperature is to be
exceeded, an optional oil cooler is available.
3. OPERATION OF GEARBOX
The zero position of the operating lever on the control console must coincide with the zero position of
the actuating lever on the transmission. Shifting is initiated by a cable or rod linkage via the actuating
lever and an actuating cam. The completion of the gear changing operation is servo-automatically
controlled.
Gear changing should be smooth, not too slow, and continuous (without interruption). Direct changes
from forward to reverse are permissible, since the multiple-disc clutch permits gear changing at high
RPM, including sudden reversing at top speeds in the event of danger.
4. OPERATION WITHOUT LOAD
Rotation of the propeller without load, e.g. while the boat is sailing, being towed, or anchored in a
river, as well as idling of the engine with the propeller stopped, will have no detrimental effects on the
gearbox.
Locking of the propeller shaft by an additional brake is not required, since locking is possible by
engaging the reverse gear. Do not sail while engaged in forward.
5. LAY-UP PERIODS
If the transmission is not used for periods of more than 1 year, it should be COMPLETELY filled
with oil of the same grade to prevent corrosion. Protect the input shaft and the output flange by means of
an anti-corrosive coating if required.
6. PREPARATION FOR RE-USE
Drain the transmission of all oil and refill to the proper level with the prescribed oil.
MAINTENANCE
1. TRANSMISSION OIL
To ensure trouble-free operation of the clutch, use only automatic transmission fluid (ATF).
Under no circumstances should the oil contain any additives such as molybdenum sulphite.
We recommend commercial Automatic Transmission Fluid (ATF), Type A or Dexron II.
