Ignition Timing
Use the
Ignition Timing
screen to check and
adjust
EMM

EMM
timing must be synchro-
nized to crankshaft position.
Refer to TIMING ADJUSTMENTS on p. 142.
Check timing after any of the following proce-
dures:
•
Powerhead replacement
•
Crankshaft replacement

IMPORTANT:
Make sure the timing pointer is
set and the outboard reaches operating tempera-
ture before making adjustments.
TPS Calibration
TPS Calibration synchronizes throttle plate open-
ing with throttle position sensor voltage.
Refer to TPS Calibration on p. 143.
Perform TPS Calibration after replacing or adjust-
ing any throttle body or throttle linkage parts.
Idle Speed Control
Use the
Idle Adjust
function to increase or
decrease IN GEAR IDLE speed. This adjustment
offsets the basic
EMM
programming and will not
set an absolute fixed speed. After the offset is
changed, the
EMM
continues to control engine
operation normally. Engine idle speed is not fixed.
