IntelliJET incorporates
the
following
improvements
over
the 1st generation technology: |
|
|
|
|
|
|
|
|
|
|
|
1. No reversing bucket
More compact system allows
larger nozzle
Eliminates danger of reversing bucket to
swimmers
Sliding fits on all moving parts
No pinch points |
2. Continuously variable
maneuvering thrust
Continuous range of
forward, neutral and reverse without stopping to shift (for example, driver can choose to be 40% in forward or reverse)
Instant response to driver
input
Eliminates gear mashing and
gear related repair bills
|
|
|
|
|
|
|
|
3. Continuously variable
power transmission in
forward mode
|
Provides more efficient
engine operation
and
better gas mileage
Increases thrust efficiency
(lower RPM
produces higher thrust for a given power input)
Reduces vibration and noise
Smooth

|
The pump and nozzle fit
neatly under the swim platform,
which is the ideal height found on popular wakeboard boats and ski boats.

The blades move to zero pitch for true neutral with no thrust in any
direction.

|
Housing removed to show
blades in reverse
position |
Reverse |
|
|
|
In reverse
pitch the blades pump water backwards through the system.
The inlet is reduced to become a nozzle for reverse thrust.
Shifting between forward, neutral, and reverse is smooth and quick,
because there are no gears to mesh.
