Breather
The gearbox must be filled with oil and the oil level checked before use. (see MAINTENANCE sec-
tion)
Using the gearbox with insufficient oil could damage the gears.
Too much oil could cause leakages through the gaskets and breather and considerably increase the
running temperature.
Under normal conditions, the drive should be reversed when the engine is idling.
In emergencies, the drive can be reversed with the engine running at maximum 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.
MECHANICAL TROLLING VALVE (M.T.V.)
The trolling valve is a device that allows the number of propeller revolutions to be changed indepen-
dently of the engine running speed. The M.T.V. is usually applied in the following circumstances:
1) when the boat speed is too high, even though the engine is idling.
2) when the rotation speed of the PTO must be greater than the propeller rotation speed.
The M.T.V. can be used in both drive directions and the maximum running speed is 900 rpm
Use instructions
Check that the M.T.V. is deselected before engaging the gear. After engaging the gear, gradually move
the M.T.V. lever until the desired manoeuvre speed is reached.
When operating with trolling valve, the number of revolutions can be changed within the limits given
above.
It is forbidden to reverse the drive when the
M.T.V. is engaged.
