Operating Temperature
An outboard run at idle speed should achieve a
temperature based on the engine's thermostatic
control. In general, the powerhead temperature
should reach at least 104°F (40°C) after five min-
utes of idling. Check that the powerhead reaches
idle temperature. Refer to SERVICE SPECIFICA-
TIONS on p. 10.

Idle Speed

Make sure the outboard idles within the specified
idle RPM range. If the outboard is run on a flush-
ing device, the idle speed and quality may not be
representative of actual in water use.
