MANOEUVRING

WARNING !
Shifting at high speed can damage both the engine and
the transmission and be dangerous for passengers.
CAUTION !
On a twin engine boat, both engines should be started
during reversing manoeuvres to reduce the risk of water
ingress in the stationary engine.
Carry out the following operations for forward / reverse
manoeuvres :
1. Reduce engine speed to idling and, if possible, let the
boat lose most of its speed.
2. Move the control lever to the neutral position and wait
a few seconds.
3. Move the control lever into astern. Increase the speed.

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).
