Note The equipment shown on this page can be ob-
tained only for propulsion engines in working boats.
Trolling valve
If the reverse gear has a trolling valve (accessory), this
should be used when the boat is to move very slowly.
Engage the trolling valve to max. slip when the reverse
gear control is in neutral. After selecting “Forward” or
“Reverse”, the trolling valve can then be set in the re-
quired trolling position within the permitted speed range.
The engine speed must never exceed 1100
rpm when using the trolling valve.
Note For full propeller power during operation, the troll-
ing valve control lever should always be in the “Disen-
gaged” position when the valve is not in use.
Disengageable clutch
The clutches have two positions on the control lever.
Lever towards engine for declutching, away from it for
neutral.
When engaging and disengaging the clutch, the en-
gine speed must not exceed 800 rpm.

1. Bilge pump

Disengageable scavenging/bilge
pump
These pumps are engaged and disengaged via electro-
magnetic connections and switches on the instrument
panel. The bilge pump has a vacuum switch which auto-
matically disengages it when the level is so low that no
water is being sucked into the pump. The vacuum
switch also has a lever for manually engaging the
pump.
The lever should be depressed 20 secs. when engaging
the pump.
