TIMING ADJUSTMENTS
7
Repeat the entire adjustment process to make
sure pointer is aligned correctly.
Install spark plugs. Refer to Spark Plug Indexing
on p. 76.
Timing Verification
Use Evinrude Diagnostics software to synchronize
the mechanical timing of the outboard with the
electronic timing of the EMM.
Check ignition timing after any of the following
procedures:
• Powerhead replacement
• Crankshaft replacement
• Flywheel removal or replacement
• CPS replacement
• EMM replacement
• EMM software replacement (reprogramming)
IMPORTANT: Make sure the timing pointer is
set and the outboard reaches operating tempera-
ture before making any timing adjustments.
TPS Calibration
Use Evinrude Diagnostics software to tell the
EMM what throttle position sensor voltage is when
the throttle plates begin to open.
Remove the air silencer.
On the Settings screen of the diagnostics soft-
ware, click the “Set TPS Calibration” button.
While holding the throttle plates closed, advance
the throttle linkage until it stops. The “Measured
TPS Calibration” field on the screen will increase.
Click the “Working” button in the software to cali-
brate the TPS.
Install the air silencer.
Set TPS Calibration after replacing or adjusting
any throttle body or throttle linkage parts.
