INTRODUCING THE MV8
ALARMS
Read the accompanying boat owner’s manual for important information
regarding alarms and gauges.
e 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. e method of alarm varies from boat model to boat model,
usually by way of a centrally mounted gauge with specic engine response.
In boats equipped with more than one engine, there will be separate alarms
for each engine.
e alarm activation will display if the following conditions occur:
• Water temperature over 215°F (102°C)
• Low oil pressure
NOTE: e engine monitor alarm will display when the ignition is turned to
the running position. e alarm will shut o momentarily. Aer the engine
is started the alarm will not go o again. If the alarm sounds or displays at
any other time or for any other reason, contact a certied Ilmor dealer before
restarting the engine.
Water Temperature
e alarm appears if the engine coolant exceeds preprogrammed limits.
If this occurs, return the engine or engines to idle for cool-down. If the
temperature is still increasing, shut engine o immediately. Conrm that
the seacock is open and that the sea strainer is clear. If neither of these are
the cause take the boat to a certied Ilmor dealer.
Oil Pressure
e alarm appears if the engine oil pressure falls below the recommended
value for the current engine speed. If this occurs, shut engine o
immediately. Check the oil level and return to normal conditions if it is
not already. Running the boat at this point represents an unknown risk. It
would be best to have the boat serviced with no further running.
