Stopping The Boat In An Emergency - Mercury Jet OptiMax 110 Manual

When the jet drive is in neutral, the impeller continues to rotate.
However, the reverse gate is positioned so that some of the
forward thrust is diverted to create reverse thrust. This
approximate balancing of forward and reverse thrust will
minimize any boat movement. Because the impeller is always
rotating and creating thrust when the engine is running, the boat
may tend to move slowly forward or backward. This is normal for
a direct‑drive jet driven boat. The operator should be aware of
this and use caution whenever the engine is running.
Avoid injury resulting from contacting the rotating impeller or
having hair, clothing, or loose objects drawn into the water
intake and wrapping around the impeller shaft. Stay away from
the water intake and never insert an object into the water
intake or water outlet nozzle when the engine is running.
The jet drive is always drawing water into the housing when the
engine is running. Do not operate the jet drive with the grate
removed from the water intake. Keep hands, feet, hair, loose
clothing, life jackets, etc., away from the water intake. Never
insert an object into the water intake or water outlet nozzle when
the engine is running.

Stopping the Boat in an Emergency

A jet powered boat has emergency stopping capability unique to
this form of propulsion.
Using the emergency stopping capability of a jet drive unit will
slow down the boat in an emergency. However, sudden
stopping may cause the occupants of the boat to be thrown
forward or out of the boat resulting in serious injury or death.
Use caution when performing the emergency stopping
procedure, and be sure to practice in a safe area.
