3.1.1 Fuel
[NOTICE]
Use of fuels not recommended in this Operation Manual may cause a decrease in
engine performance and cause components to fail.
(1) Selection of fuel
Use the following diesel fuels for best engine performance:
ISO8217 DMA, BS2869 A1 or A2
Fuels equivalent to Japanese Industrial Standard, JIS. No. K2204-2
Cetane fuel number should be 45 or greater
(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.
Pump up only fuel above the down half, leaving
dreg accumulated on the bottom.
