Check for fuel leakage regularly.
If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
outboard unsafe to operate.
Check the fuel lines for leaks, crack, or mal-
function. If a problem is found, your Yamaha
dealer or other qualified mechanic should re-
pair it immediately.

Inspecting idling speed
WARNING
EWM00450
Do not touch or remove electrical parts
when starting or during operation.
Keep hands, hair, and clothes away from
the flywheel and other rotating parts
while the engine is running.
2-hp models: The propeller rotates
whenever the engine is running. Do not
move the throttle control lever from the
start position during warm-up. The boat
could unexpectedly start to move, which
could result in an accident.
CAUTION:
ECM00490
This procedure must be performed while
the outboard motor is in the water. A flush-
ing attachment or test tank can be used.
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.
