4.3.3 Restarting After Starting Failure

When attempting to restart the engine after starting failure, be sure that the engine is at a complete

stop before turning the starter switch key. If the engine is restarted while the engine still has not

stopped, the pinion gear of the starter motor will be damaged.

●

When the engine will not start after several

attempts, check the fuel system. If there is

air in the fuel system, the fuel will not be fed

and starting will not be possible.

After bleeding air from the system, attempt to

restart the engine. →See 3.2.2

(2) Checking for problems

While warming up the engine, check the following items.

①Check that the meters and alarm devices on the control panel are normal. →See 2.5.2

②Check for water or oil leakage from the engine.

③Check that exhaust color, engine vibrations and sound are normal.

④Check that sufficient cooling water is discharged from the seawater outlet pipe.

Operation with too little 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 clogged ?

●

Is the seawater suction hose broken, or does the hose suck in air due to a loose joint ?

4.3.4 After the Engine has Started

(1) Warming-up running

After the engine has started, let it run for

about 5 minutes. This warms up the engine

and distributes oil to all of the parts.

■Morse Remote Control Handle

① Leave the remote control handle in

NEUTRAL.

②Pull out the handle lever (MT-3) or the

free throttle button (MV) and adjust

the speed to no more than 1500rpm and

run the engine at low speed with no load.

Do not hold the starter switch on for

more than 15 seconds at a time. If the

engine does not start the first time, wait

for about 15 seconds before trying

again.

[NOTICE]

The engine will seize if it is operated

when cooling seawater discharge is too

small or if load is applied without any

warming up operation.

[NOTICE]
