INSTALLATION AND PREDELIVERY
RUNNING CHECKS
2
Tachometer Pulse Setting
Confirm accuracy of tachometer reading.
•
Adjust dial on back of tachometer to required
setting (the outboard should not be running).
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. Refer to
TECHNICAL DATA on
p. 18.
Idle Speed
Outboard idle speed is essential for proper out-
board control and shift function. Make certain the
outboard idles within the specified idle RPM
range. If the outboard is run on a flushing device,
the idle speed and quality may not be representa-
tive of actual “in water” use.
Break-In
When the outboard is delivered, the customer
should be referred to the correct break-in proce-
dure in the
Operator’s Guide .
The Engine Management Module (
EMM
) on new
Evinrude E-TEC
models is programmed to auto-
matically supply extra oil to the engine during the
first few hours of operation above 2000 RPM.
The dealer may use the Diagnostic Software pro-
gram to confirm that the break-in program has
been initiated. Refer to
Oil Control on p. 98.
