WARNING

 

EWM00420 

 

 

Before starting the engine, make sure
that the boat is tightly moored and that
you can steer clear of any obstructions.
Be sure there are no swimmers in the
water near you.

 

 

When the air vent screw is loosened,
gasoline vapor will be released. Gaso-
line is highly flammable, and its vapors
are flammable and explosive. Refrain
from smoking, and keep away from
open flames and sparks while loosen-
ing the air vent screw.

 

 

This product emits exhaust gases
which contain carbon monoxide, a col-
orless, odorless gas which could cause
brain damage or death when inhaled.
Symptoms include nausea, dizziness,
and drowsiness. Keep cockpit and cab-
in areas well ventilated. Avoid blocking

 

exhaust outlets.

 

1.

If there is an air vent screw on the fuel
tank cap, loosen it 2 or 3 turns.

2.

If there is a fuel joint or a fuel cock on the
boat, firmly connect the fuel line to the
joint or open the fuel cock.

3.

Squeeze the primer pump with the outlet
end up until you feel it become firm.
