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.

Engine Flushing

Flush the outboard with fresh water following each
use in brackish, salt, or polluted water to minimize
the accumulation of scale and silt deposits in cool-
ing system passages.
The outboard can be flushed on the trailer or at
dockside; running or not running.
IMPORTANT:
The outboard must be located in
a well ventilated area with appropriate ground
drainage during the flushing procedures.
Keep water inlet pressure between 20 to 40 psi
(140 to 275 kPa).
