TROLLING VALVE
The Trolling valve system allows to reduce the rotation
speed of the propeller below its speed when the engine
is at idle. The boat speed is reduced by 30% to 70%.
CAUTION !
The Trolling valve system must never be used for
manoeuvring. It also must never be used at an engine
speed of more than 1200 rpm (refer to Gear Box
operating manual).
AFTER RUNNING
STOPPING THE ENGINE
CAUTION !
Never stop the engine by using the main switch. This
could damage the electrical system.

cool down the engine.

engine stops, all lamps go out. For panel without
