Steering Your Boat
The jet drive is dependent on water jet thrust for steering the boat. The jet drive has
a steerable outlet nozzle that directs this water jet thrust to the right or left. If the water
jet thrust should ever stop, (water blockage, the engine stops, or, etc.) will cause the
boat to slow to a stop. However, while slowing there will be a reduced ability to steer
the boat.
While steering your outboard, you will find quick response to the helm, but due to the
relatively flat-bottom hulls and lack of a gear case in the water, your boat will tend to
skid on the turns. You must start your turns early and use sufficient power to maintain
steering control.
WARNING
Avoid serious injury or death. Do not attempt to steer your boat into a tight
turn; at too high a speed, your boat could “spin out” or even roll over,
resulting in occupants being thrown within the boat or out of the boat.
WARNING
Avoid injury, death or property damage resulting from collision due to loss
of directional control. Directional control is derived from the water jet thrust.
Thus, caution should be exercised when maneuvering at higher speeds in
areas where debris (weeds, logs, gravel, etc.) could be picked up into the jet
drive. This can cut off or reduce the water jet thrust, thereby directly affecting
boat directional control. Boat directional control can also be substantially
reduced or lost altogether by a sudden loss of power such as running out of
gas, quickly backing off throttle, turning off ignition switch, or activating
lanyard stop switch. Remember your ability to take evasive action is
dependent on sufficient water jet thrust to control your boat.
