Routine Service
Propellers
SystemCheck — The SystemCheck monitor self-
tests by sounding a half-second beep. System-
Check gauges self-test by turning the indicator
lights on simultaneously, then off in sequence.
Water Pump Overboard Indicator
A steady stream of water should flow from the
overboard indicator.
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.
Leaks
Perform running checks of the as follows:
•
Start outboard.
•
Inspect all fuel hoses and connections.
•
Inspect all oil hoses and connections.
•
Inspect all cooling water hoses and connec-
tions.
•
Repair any leaks or misrouted hoses immedi-
ately.
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
Evinrude E-TEC outboards require no break in.
When the outboard is delivered, refer the cus-
tomer to the Oiling System information in the
Operator’s Guide .
Propellers
Propeller Selection
Water testing with various propeller designs and
sizes is the best method of propeller selection.
The correct propeller, under normal load condi-
tions, will allow the engine to run near the mid-
point of the RPM operating range at full throttle.
Refer to
SERVICE SPECIFICATIONS in the Ser-
vice Manual for RPM range.

CAUTION
Selection of the wrong propeller could reduce
engine service life, affect boat performance,
or cause serious damage to the powerhead.

NOTICE
If the propeller blades have too much pitch,
the engine will operate below its normal range
at full throttle. Power will be lost, and power-
head damage could occur. If the propeller
blades have too little pitch, the engine will
operate above its normal range and damage
from overspeeding could occur.
