3.1.1 Fuel

(1) Selection of fuel

Use the following diesel fuels for best engine performance:

ISO8217 DMA, BS2869 A1 or A2

(2) Fuel Handling

1) Water and dust in the fuel oil can cause

operation failure.

Use containers which are clean inside to store

fuel oil. Store the containers away from rain

water and dust.

2) Before supplying fuel, let the fuel container

rest for several hours so that water and dust

in the fuel are deposited on the bottom. Pump

up only the clean fuel.

3) Use fuel with a Cetane number of over 45.

4) When supplying fuel to a new boat for the

first time, be sure to extract all fuel from the

F. O. tank and check for impurities in the fuel.

(3) Fuel piping

Install the piping between the fuel tank and the

engine's fuel injection pump, as illustrated on

the right.

Be sure to install a drain cock at the bottom of

the fuel tank to remove water and dust.

Install an oil/water separator (optional) and a

fuel filter in the middle of the fuel piping.

Use of fuels not recommended in this Operation Manual may cause a decrease in

engine performance and cause components to fail.
