3. Operation
If you have never driven a jet boat before, familiarise yourself with the
separate guide “Steering and controlling jet boats” before driving the boat for
the first time.
3.1. Starting
Before you start the engine equipped with the jet, make sure that
• the reversing deflector control lever is in centre position
• the gear is disengaged. (If the engine has no gearbox, it must be in the idle
position before you start it.)
• Note the direction of the jet’s rotation, which usually corresponds to the
direction of the engine’s rotation (counterclockwise from the rear of the
boat). This is why the gear must usually be used in the "reverse" position.
The positions of the reversing deflector control lever are described in section
3.3.

manufacturer's instructions about running in during the first few drives.
Ensure the functioning of the jet carefully when driving at low speeds.
DANGER!
The jet can be dangerous when running.
Do not go near the rotating parts.
Do not open the jet's inspection hatch when the engine is
running.
When running, the jet propulsion unit sprays water backwards
at great pressure. Make sure that there is no one in the water
behind the boat!
The intake in the bottom of the boat causes suction power at
the back of the boat when the jet propulsion unit is running.
Make sure that there is no one in the water at risk of being
affected by the intake.
When you start the engine for the first time, you may hear a jingling sound for
a few minutes. This is normal and the sound will disappear when the impeller
