Even with high temperature alarms installed, it is
important that you visually monitor both temperature
gauges while running the engines. If a temperature
gauge indicates excessive engine temperature, immedi-
ately shut down the affected engine.
The engine manufacturer has established a maximum
coolant temperature rating for your engines, as listed
in the engine OEM information. Do not exceed the
maximum coolant temperature. Doing so could dam-
age the engines.
Oil Pressure Gauge
The oil pressure gauge displays the pressure within the
engine's lubrication system. The oil pressure reading
changes as engine speed changes. However, a noticeable
decrease (either sudden or gradual) in an engine's oil
pressure while the boat is maintaining a constant speed
may indicate an oil pump failure, a leak in the lubrica-
tion system or excessive engine wear.
Each engine is equipped with a pressure alarm. The
alarm sounds when the pressure in the lubrication
system decreases to a predetermined point. The alarm
also sounds when the engine is started or when the
ignition switch is "ON" and the engine is not running.
In these situations, the engine does not yet have ad-
equate oil pressure; the alarm is silenced as soon as the
oil pressure increases to within the normal operating
range. Refer to the engine OEM information for the
normal operating range.
If the alarm sounds after the engine has been running
for a while, or if the alarm is not silenced within 15
seconds after starting the engine, check the oil pressure
gauges. If either gauge indicates abnormally low oil
pressure, immediately shut down the affected engine.
Even with the low oil pressure alarms installed, it is
important that you visually monitor both oil pressure
gauges while running the engines. If a pressure gauge
indicates low oil pressure, immediately shut down the
affected engine.

A cold engine has a tendency to
stall when first put into gear. Let
your engines warm up a few
minutes before departing your
dock or anchorage.
