DESCRIPTION AND USE OF OPERATOR CONTROLS AND INDICATORS
THROTTLE/TRANSMISSION CONTROLS
A
ENGINE THROTTLE/TRANSMISSION CONTROL LEVERS--Dual-lever
action controls located to the right of the steering wheel. The left lever controls
port transmission and rpm engine speed. The right lever controls the starboard
transmission and rpm engine speed.
Pushing the levers forward engages transmission into forward gear and engine
to drive hydrojet units so that water is ejected through nozzles at the back of
the boat. Putting levers in neutral position disengages the transmission.
Pulling the levers backward into reverse position engages the transmission to
drive the hydrojet units in reverse so that water enters the nozzles and is
ejected through the inlet grills at the bottom of the boat. The reverse position
is used only to clean debris from the grille and is not to be used to control the
boat
The levers have dual positions and functions:
1. Levers retracted inward control shifting and engine rpm speed.
2. Levers pulled outward control engine rpm speed only.
The left lever controls the port side engine throttle/transmission control handle
and the right lever controls the starboard side engine throttle/transmission
control handle. This allows the operator to control the revolutions per minute
(rpm) of each engine and forward speed.
