The drive line on the boat is direct drive,
so jet thrust is always being produced
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 position
when Neutral is selected. The boat
will start moving as if it was in For-
ward or Reverse if engine speed is
increased above idle in Neutral.

Reverse
The jet pump gates are dropped all the
way down over the jet nozzles. Jet thrust
is redirected toward the bow of the boat,
which moves the boat backward.
