proximately 125 m (410 ft) after the throttle le-
ver is released or the engine is stopped,
although this distance will vary depending on
many factors, including gross weight, water
surface conditions, and wind direction.
If the RiDE lever is squeezed to slow down,
the stopping distance is approximately 30%
shorter than when the RiDE lever is not used.
However, this distance will vary depending
on many factors, including gross weight, wa-
ter surface conditions, and wind direction.
EWJ01793
Allow adequate stopping distance. Stay
far enough away from others so you can
always safely coast to a stop.

member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power to
steer away from a boat or other obstacle
that comes into your path.
To avoid rear-end collisions while oper-
ating the watercraft, check behind you
before using the RiDE lever to slow
down or stop the watercraft.
