WARNING
Do not touch or remove electrical parts
G
when starting or during operation.
Keep hands, hair, and clothes away from
G
the flywheel and other rotating parts
while the engine is running.
2-hp models: The propeller rotates

CAUTION:
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.
