Keep hands, hair, and clothes away from
the flywheel and other rotating parts
while the engine is running.

4.
Install the filter element and filter cup into
the filter housing.
Tighten the ring nut so that one of the
larger ring nut tabs is aligned with the lock
tab.
CAUTION:
This procedure must be performed while
the outboard motor is in the water. A flush-
ing attachment or test tank can be used.
5.
A diagnostic tachometer should be used for
this procedure. Results may vary depending
on whether testing is conducted 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-hp
model: Warm the engine with the
throttle in the start position or less. If the
outboard is mounted on a boat, be sure
the boat is tightly moored.
6.
Run the engine and check the filter and
lines for leaks.
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty veri-
fying the idle speed, or the idle speed requires
adjustment, consult a Yamaha dealer or other
qualified mechanic.
NOTE:
If any water is in the fuel, the red ring in the
fuel filter unit will float. If so, remove the cup
and drain the water.
