3. Fuel System
It is recommended to install an additional fuel/water separator on the boat to effectively remove water and foreign
substances contained in the fuel. If a fuel/water separator of a wrong size is added to the fuel system, this may restrict
the fuel and lead to the engine stalling or being damaged due to fuel starvation. Use of a valve fitting of a wrong size
may also cause similar problems.
1) Fuel
Avoid using old gasoline or gasoline contaminated with debris, sand, mud, and other impurities during and after the
break-in operation of the engine.
Do not use a mixture of gasoline and oil as
fuel in this engine.
Recommended Fuel/Water Separator Size:
Flow Rate: 50 L/H (13 GPH) or more
Filter Rating: 10 Micron
2) Engine Oil
1. Engine needs to be vertical position.

secure the tank.
