Function Test
1. Attach the lanyard lock clip to the stop switch.
2. Start the engine.
3. With engine running, pull the lanyard to disengage the lock clip.
Engine should stop running.
The stop switch is designed to also operate as a
pushbutton switch with the lanyard left attached.
Repeat the test but do not remove the lanyard. Press down firmly
and hold the stop switch until engine stops running. If engine
continues to run in either test, the stop switch or wiring are faulty
and must be replaced before engine is operated, see Section 7.

OPERATOR ALERT SYSTEMS

To help protect the engine from serious powerhead damage, it is
advisable to test the operator alert systems at the start of each
boating season and periodically during the season.
Warning Horn Test
A warning horn is built into the prewired remote control box or is
wired separately on tiller models. The horn emits a constant tone to
alert the operator of critical operating conditions. Depending on
engine model, these conditions may include:
• Clogged or obstructed cooling water intake
• Engine overheat
• Low oil level in oil automixing tank
Disable the ignition system to prevent accidental
engine startup.
1. Place the remote control lever (if equipped) in the FORWARD or
REVERSE position.
2. Turn the main switch key to the ON position.
3. Remove the cover from the electrical box.
