sembled unit. The interface with boat wiring follows established practices and conforms
to regulatory guidelines. Every reasonable effort has been made to make the electrical
connection simplified and straightforward. Consumers are strongly encouraged to seek
assistance from authorized ILMOR dealers when dealing with electrical issues.
Do not realign the wiring or in any way alter the wiring of the MV8 engine. Doing so
may result in damage to the engine, which is not covered under warranty, and suf-
ficient voltage may be present to cause serious injury and/or death.
One of the reasons
eral sensors monitor performance any time the engine is running. Among the sensors are
the throttle position, manifold absolute pressure (MAP), camshaft position, crankshaft
position, coolant temperature, knock, oxygen, catalytic converter exhaust, oil pressure,
oil temperature, and coil pack-to-crankshaft sensors. Because nearly all sensors are located
inside sealed areas of the engine, and diagnostics are normally done utilizing highly techni-
cal and expensive tools, consumers are urged to take the boat to an authorized ILMOR
dealerships for analysis if or when a malfunction is suspected.
Often issues will be brought to the consumer's attention by way of alarms. Most sen-
sors trip alarms, whether audible or visual on the gauges. No warning should be ignored.
Occasionally, a sensor will malfunction, but in most instances the sensor is correctly iden-
tifying and coding problems for analysis.
Boats are equipped with a variety of audible and visual alarms that alert operators
to potential performance issues. No alarm, whether it sounds an alert or provides
information on the gauges, should ever be ignored. The drive train's sensors are often
the earliest indication of problems that, if ignored, may result in serious damage to
the equipment. This is not covered under warranty.

tant information regarding alarms and gauges.
The ILMOR engine alarm system utilizes a visual alarm to indicate a condition in which
any of the monitored engine parameters fall out of the nominal operating range. In all cases,
the proper response to the alarm is to throttle back immediately and check the gauges to see
which system is out of range. The method of alarm varies from boat model to boat model,
usually by way of a centrally mounted gauge with specific engine response. In boats equipped
with more than one engine, there will be separated alarms for each engine.
The alarm activation will sound if the following conditions occur:
Water temperature over 199 F. (93 C.) - Open Cooled
Water temperature over 239 F. (115 C) - Close Cooled
Low oil pressure
NOTE: T he engine monitor alarm will display when the ignition is turned to the
running position. The alarm will shut off momentarily. After the engine is started
