DESCRIPTION AND USE OF OPERATOR CONTROLS AND INDICATORS (Contd)
B
SCOOP CONTROL LEVERS--Scoop controls are located to the right of
throttle/transmission control levers and above the auxiliary switch panel. The
left lever controls the port side scoop (reverse deflector) and the right lever
controls the starboard side scoop (reverse deflector), allowing operator to
control direction of output from hydrojet nozzles to obtain forward and reverse
direction of boat. In addition, the scoop controls may be used to assist in boat
maneuvering and controlling speed.
WARNING
Scoop control levers should not be moved from full ahead
to reverse at high engine rpm. Failure to comply may
result in death or injury to personnel and damage to
equipment.
NOTE
Scoop controls will not function unless
throttle/transmission control levers are placed in forward
position to start hydrojets.
Before scoop controls can move, the throttle/transmission
control levers must be placed in forward position to start
hydrojets.
Putting the levers in the center position allows the thrust from the hydrojets
to be deflected downward and the boat to remain stationary. Pushing the
levers forward raises the scoops, increases the forward thrust, and moves the
boat forward. Pushing the levers all the way forward allows full forward
thrust. Pulling the levers back lowers the scoops. This deflects the thrust from
the hydrojets to the front and moves the boat backwards. Pulling the levers all
the way back allows full backward thrust. The levers can be set at any position
from full forward to full back. Levers can be operated independently of each
other for effective steering at low engine rpm.
