E.R.
The rotation direction matches the engine rotation.
C.E.R.
The rotation direction is contrary to the engine rotation.
The marine gearbox can be supplied with or without accessories (heat exchanger, flexible coupling, brackets, trolling
valve).
The marine gearbox is supplied without oil.
Before putting the marine gearbox into operation, the oil must be topped up and its level checked. (Refer to
section "Maintenance" (p. 20)).
Using the marine gearbox with too little oil can damage the gears.
Excessive oil can cause sealing rings leakages and bleedings and can considerably increase the operating tem-
perature.
In normal operating conditions, the direction reversals must be made with the engine at minimum power.
In case of emergency, the direction of motion can be reversed with the engine at full speed.
Repeatedly reversing the drive with the engine running at maximum speed will considerably shorten the life of
the clutches
Make sure the engine and propeller are at a standstill before carrying out any kind of operation on the gearbox.
