Section 06 STEERING AND PROPULSION

Subsection 02 (iBR AND VTS)

NOTE: The iBR lever must be pulled in at least

25% of its travel (approximately) before the iBR

gate starts to move. The first 25% of iBR lever

travel has no effect on the iBR gate.

Every time the iBR gate moves when commanded

by the iBR lever, engine RPM is momentarily re-

duced to idle speed as the gate moves.

WARNING

If it is necessary to remove any foreign ob-

ject caught in the iBR gate, nozzle or linkages,

strictly observe the following before proceed-

ing:

– Remove D.E.S.S. key from post.

– Wait at least 5 minutes.

– Do not press on START/STOP button. If

START/STOP button is pressed, wait an-

other 5 minutes.

Forward Mode

To engage f

orward:

– Start engine

– Tap on the throttle lever.

The iBR gate will automatically move to the for-

ward position (full up).

NOTE: The

full up position of the iBR gate is de-

pendent o

n the selected VTS trim position.

Reverse Mode

If the wat

ercraft speed is below 8 km/h (5 MPH)

when the i

BR lever is pulled in, reverse mode is

engaged.

When the iBR lever is pulled in to engage reverse,

the following occurs:

–EngineR

PM is reduced to idle.

– The iBR gate moves to the reverse position.

– Engine RPM ramps up to the engine power

commanded by the throttle lever.

When operating in reverse mode, the iBR lever

controls the iBR gate position and the engine RPM

is controlled by the throttle lever.

The iBR g

ate position can be modulated anywhere

betwee

n the neutral and full reverse positions de-

pendin

g on the position of the iBR lever. If the

iBR lev

er position is varied during reverse opera-

tion, e

ngine RPM is reduced to idle every time the

iBR gat

e moves. It is therefore recommended to

maint

ain the iBR lever completely pulled in.

Maximum engine RPM in reverse is 5000 RPM.

Braking Mode

If the watercraft speed is 8 km/h (5 MPH) per hour

and above when the iBR lever is pulled in, braking

mode is engaged.

When the iBR lever is pulled in to engage braking,

the following occurs:

– Engine RPM is reduced to idle.

– The iBR gate moves to the maximum down po-

sition.

– Engine RPM ramps up to the engine power

commanded by the iBR lever.

When operating in braking mode, the iBR gate al-

ways moves to the maximum down position. The

throttle lever signal is overridden and engine RPM

is now dependent on watercraft speed and how

far the iBR lever is pulled in.

If watercraft speed is high when braking is ap-

plied, engine power will be initially low and

then ramp up to the power commanded by the

iBR lever position. The engine RPM may be in-

creased, as necessary, to apply a stronger braking

effect with the jet pump thrust when the condi-

tions dictate.

As the watercraft slows to less than 8 km/h

(5 MPH), the following occurs:

– Braking mode ceases.

– Reverse mode takes over if the iBR lever is not

released.

– Throttle control reverts back to the throttle

lever.

Neutral Mode

Every time the iBR lever is pulled in and released,

the iBR gate will default to the neutral position

except if the throttle lever is still pulled in when

the iBR lever is released. If the throttle lever is

still pulled, the iBR gate will move to the forward

position when the iBR lever is released and the

watercraft will accelerate forward.

iBR Override Function

To permit easy access to the jet pump, nozzle, iBR

gate, and various linkages for inspection, mainte-

nance, cleaning or removal of debris, the iBR sys-

tem provides for an iBR override function which,

is accessible through the information center.

When iBR override is activated, it allows the

user to electrically move the iBR gate and nozzle

through its full range of motion using the VTS

control button.
