Fuel

Air
Venting Proc
edures
1. Check the fuel level in the fuel tank.
Replenish if insufficient.
2.
Loosen the air vent bolt at the top
of
the oil/water separator by turning
it
2
or
3 times. When fuel which does not con-
tain air
bubbles comes out
of
the bolt
hole,
tighten the air vent bolt.
3.
Loosen the air vent bolts of the fuel
filter
and the fuel injection
pump
by
turning them 2 or 3 times.
4.
Feed fuel with the fuel feed
pump
by
moving the lever on the left side of the
feed pump up and down.
5.
Allow the fuel containing air bubbles to
flow out from the air vent
bolt holes.
When the fuel coming out no longer
contains bubbles, tighten the air vent
bolts.
This completes the air venting
of
the
fuel system. Try starting the engine
aga1n.

After
the
Engine has
Started
After the engine has started, check the
following items at a low engine speed:
1. Check that the gauges and alarm
devices on the instrument panel are
normal.
2.
Check for water
or
oil leakage from the
eng1ne.
3.
Check that exhaust colour, engine vi-
brations and sound are
normal.
4.
When there are no problems, keep the
engine at
l
ow
speed with the boat still
stopped to send lube oil
to
all parts
of
the engine.
5.
Check that sufficient cooling water is
discharged from the seawater
outlet
pipe. Operation with too small seawater
discharge
will burn the impeller
of
the
seawater pump.
If
seawater discharge is
too
small,
stop
the engine immediately.
Identify the cause and repair.
• Is the Kingston
cock
open?
• Is the inlet
of
the Kingston cock on
the
hull bottom clogged?
• Is
the seawater suction hose broken,
or does the hose suck in air due to a
loose joint?
The
engine
will
se
ize
if it
is
operated
when
cooling
seawater
dischar
ge
is
too
s
mall
or
if
load
is
applied
without
any
warming
up
