NOTE: This boat is equipped with a
mechanical interlock that prevents shift
lever movement unless both throttle
levers are put in the idle position first. It
also has a start-in-gear protection neu-
tral switch that prevents the engines
from cranking if the shift lever is not in
Neutral.

The shift lever controls the direction of
travel.
The drive line on the boat is direct
drive, so jet thrust is always being pro-
duced while the engines are running.
The direction of the boat is controlled
by jet pump gates which direct the flow
of the jet thrust as follows:
Forward
The jet pump gates are lifted all the
way up. All jet thrust is to the rear,
which moves the boat forward.

Neutral
The jet pump gates are dropped down
part way over the jet nozzles. Some jet
thrust is to the rear and some jet thrust
is redirected forward. This balance of
thrust acts like "neutral" to keep the
boat from moving.
WARNING
Leave the throttles in the idle posi-
tion when Neutral is selected. The
boat will start moving as if it was in
Forward or Reverse if engine speed
is increased above idle in Neutral.
