INSTALLATION AND PREDELIVERY
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.
Break-In
When the outboard is delivered, refer the cus-
tomer to the break-in information in the Opera-
tor's Guide.
The Engine Management Module (EMM) auto-
matically supplies extra oil to the engine during
the first five hours of operation, above 2000 RPM.
Use the diagnostics software to confirm that the
break-in program has been started. Refer to Oil
Control Settings on p. 106.
