Inspecting Idle Speed; Changing Engine Oil - Yamaha F200 Owner's Manual

1. Spark plug gap
2. Spark plug part number
3. Spark plug I.D. mark (NGK)
Spark plug gap:
1.0–1.1 mm (0.039–0.043 in)
5. When fitting the plug, wipe off any dirt
from the threads, and then screw it in to
the correct torque.
Spark plug torque:
25 Nm (2.55 kgf-m, 18.4 ft-lb)
TIP:
If a torque-wrench is not available when you
are reinstalling a spark plug, a good estimate
of the correct torque is 1/12 turn past finger-
tight. When you are installing a new spark
plug, a good estimate of the correct torque is
1/2 to 2/3 turn past finger-tight.
6. Install the ignition coil and tighten the
bolts.
Bolt tightening torque:
7 Nm (0.71 kgf-m, 5.2 ft-lb)
7. Install the ECM (Electronic control mod-
ule) cover and tighten the bolts.
Bolt tightening torque:
8 Nm (0.82 kgf-m, 5.9 ft-lb)

when starting or during operation.
 Keep hands, hair, and clothes away
from the flywheel and other rotating
parts while the engine is running.

NOTICE
This procedure must be performed while
the outboard motor is in the water. A flush-
ing attachment or test tank can be used.
If the boat is not equipped with a tachometer
for the outboard motor, use a diagnostic ta-
chometer for this procedure. Results may
vary depending on whether testing is con-
ducted with the flushing attachment, in a test
tank, or with the outboard motor in the water.
1. Start the engine and allow it to warm up
fully in neutral until it is running smoothly.
2. Once the engine has warmed up, verify
whether the idle speed is set to specifi-
cation. For idle speed specifications, see
page 14. If you have difficulty verifying
the idle speed, or the idle speed requires
adjustment, consult a Yamaha dealer or
other qualified mechanic.
