3. Operation

5. Check that sufficient cooling water is

discharged from the seawater outlet

pipe. Operation with too small seawa-

ter discharge will burn the impeller of

the seawater pump. If seawater dis-

charge 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 full bottom clogged?

• Is the seawater suction hose bro-

ken, or does the hose suck in air

due to a loose joint?

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.

3.3.3 Operation

(1) Engine Acceleration and Decelera-

tion

Use the governor handle to control

acceleration and deceleration. Move the

handle slowly.

(2) FORWARD-NEUTRAL

(boat stopped) - REVERSE Clutch

Use the clutch handle to change from

FORWARD to NEUTRAL (boat stopped)

to REVERSE.

Shifting the clutch while operating at high

speed or not pushing the handle fully into

position (half clutch) will result in damage

to clutch parts and abnormal wear.

1. Before using the clutch, be sure to

move the governor handle to a low

speed position (1000 rpm or less).

Move the governor handle to a high

speed position after completing clutch

operation.

2. When changing between FORWARD

and REVERSE, bring the clutch to

NEUTRAL and pause before slowly

shifting to the desired position. Do not

shift abruptly from FORWARD to

REVERSE or vice versa.

3. Move the clutch handle accurately and

fully into the FORWARD, NEUTRAL,

and REVERSE positions.

3.3.4 Cautions During Operation

Always be on the lookout for problems

during engine operation.

Pay particular attention to the following:

(1) Is sufficient water being dis-

charged from the seawater outlet

pipe?

If the discharge is small, stop the engine

immediately, identify the cause and repair.

(2) Is the exhaust colour normal?

The continuous emission of black exhaust

indicates engine overloading. This

shortens the engine’s life and should be

avoided.
