3. Fuel System

It is recommended to install additional large sized fuel/water separator on the boat to effectively remove water and foreign
substances contained in the fuel. At the same time however, note that the fuel filter added to the fuel system may prevent
smooth flow of fuel, possibly causing the engine to stall at low speeds, or fuel to be lean at higher engine speed resulting in
giving damage to the engine. Use of valve fitting can also cause similar troubles.
WARNING
To prevent damaging to the engine, use the
following steps to prime the electric oil
pump, pressure-feed the oil, and air-purge
the oil in the order described below before
starting the engine initially after the
installation of the outboard motor.

1) Fuel

Avoid the use of old gasoline or gasoline containing impurities such as sand or mud in any occasion such as break-in
operation of the engine and even after the break-in.
WARNING

oil for this engine.

2) Oil

Use Genium MD Oil. (Oil for two stroke direct injection engine recommended by the outboard manufacture)
Use of low quality engine oil can cause serious
damage to the engine.

3) Electric Fuel Pump

Electric fuel pump pressure, if used in conjunction with engine mechanical fuel pump, must be limited to no more than 0.03
MPa (4 psi) [0.3kg/cm 2 ].
