ENGINE SENSORS
One of the reasons the Ilmor High-Performance Marine engines are
reliable and well running is that several sensors monitor performance any
time the engine is running. Among the sensors are the throttle position,
manifold absolute pressure (MAP), camsha position, cranksha position,
coolant temperature, knock, oil pressure and oil temperature. Because
nearly all sensors are located inside sealed areas of the engine, and
diagnostics are normally done utilizing highly technical and expensive
tools, consumers are urged to take the boat to an authorized Ilmor High-
Performance Marine service center for analysis if or when a malfunction is
suspected.
Oen issues will be brought to the consumer’s attention by way of alarms.
Most sensors 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 identifying and coding problems for
analysis.
NOTICE: Always pay attention to the audio and visual alarms. 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, and
if ignored, may result in serious damage to the equipment. This is not
covered under warranty.
