Operation
Trolling (option)
The Trolling function is only available for engines with
hydralic reverse gear.
Trolling requires two control levers, one for throttle/
gear, and the other to control the slip function. Trolling
makes it possible to use higher engine power without
increasing boat speed.
WARNING! If engine speed exceeds the maxi-
mum permissible engine speed for trolling (ap-
prox. 1000 rpm, depending on reverse gear), the
EVC system automatically disengages trolling
and full propeller effect returns. Depending on
the position that the control lever is in when au-
tomatic disengagement occurs, the boat speed
can increase rapidly.
Operation
Move the throttle/gear lever to a position where the
engine speed is within the permissible engine speed
range and move the slip control lever to a slip posi-
tion. Active Trolling is indicated by an icon, on the
tachometer display (B).
IMPORTANT! If Trolling initializing icon, , is
shown on the tachometer display (A), Trolling is
not ready to use. Normal gear shifting until Trol-
ling is activated.
NOTE! At maximum slip there is no propeller effect.
Move the slip control lever to minimum slip position to
deactivate Trolling. The indication in the tachometer
display goes out.
IMPORTANT! Delay in gear shifting may occur
when Trolling is active.
Trolling initializing - Trolling is
not ready to use. (Twin disc)
