ENGINE MANAGEMENT MODULE (EMM)
EXTERNAL SENSORS
If cylinder head temperature exceeds 212° F
(100° C) above 3500 RPM, or 230° F (110° C)
below 3500 RPM, the EMM:
40 - 65 HP MODELS
If cylinder head temperature exceeds 212° F
(100° C), the EMM:
If cylinder head temperature exceeds 248°F
(120°C), the EMM:
ALL MODELS
The outboard will not restart after a temperature
related SHUTDOWN until the engine temperature
returns to normal. Refer to SHUTDOWN MODE
on p. 66.
If sensor values are less than -15°F (-26.1°C) or
greater than 332°F (166.5°C), the EMM:
If sensor values are below -4°F (-20°C), the EMM:
If cylinder head does not reach operating temper-
ature (104°F / 40°C below 2300 RPM) in 10 min-
utes, the EMM:
Low Oil Switch
The low oil switch monitors the oil level in the oil
tank.
If the oil level falls below one-quarter capacity, the
EMM signals:
When the oil level falls below one-quarter, the
EMM begins counting oil pump pulse cycles.
When it reaches:
• 40 – 65 HP: 4800 pulses
• 75 – 90 HP: 6000 pulses
the EMM:
To recover from S.A.F.E. mode, the oil pump must
cycle for a minimum of three pulses with the oil
level above one-quarter.
If outboard has been run for more than 3 hours
with NO OIL faults (codes 34 & 117), the EMM
