STOPPING THE ENGINE

To stop the engine, return the throttle
lever to the idle position, then turn the
main switch to "Off." The engine can
also be stopped by pulling the engine
stop switch lanyard.
WARNING
Once the engine has stopped, you
have NO STEERING CONTROL over
the boat. You could collide with
another boat, a dock, or other
obstacle.
_________________
NOTE:
● Remove the ignition key and the
engine stop switch lanyard if the
boat will be left unattended.
● Stopping the engine immediately
after operating at high rpm is not
recommended. Let the engine cool
off at idle or low speed for a few
minutes first.
________________
BREAK-IN (RUNNING-IN)
PROCEDURE
The engine and other components
require a break-in (running in) period to
allow surfaces of moving parts to wear
in evenly. This ensures proper perfor-
mance and promotes longer engine life.
CAUTION:
● Failure to follow the break-in pro-
cedures may result in reduced
engine life, or even engine damage.
● During first 5 hours or 2 tanks of
operation, use 50:1 pre-mix fuel
(in addition to oil in oil tank).
● After above period, use straight
gasoline (petrol) for normal oper-
ation.
1) Before launching: Fill the fuel tank
with 50:1 premix fuel. Fill the oil tank
with oil (see page 3-3). Launch the
boat and start the engine (see page
3-11).
2) First 5 minutes: Run the engine at
the lowest possible idling speed.
3) First tankful of fuel: Gradually
increase the throttle position during
operation, up to a maximum of one-
half throttle. Vary engine speed
occasionally.
4) Second tankful of fuel: Fill the tank
again with 50:1 premix fuel (in addi-
tion to the oil in the oil tank), and
proceed with normal operation.
Following this tankful of fuel, use
straight gasoline in the fuel tank and
oil in the oil tank (see page 3-3).
