Indmar Marine Engines
Fresh Water (Closed) Cooling Systems
Some engines have
a closed fresh water
cooling system. In the
fresh water system
the cooling water
contains anti-freeze
and re-circulates
throughout the
engine. If your engine
is equipped with a
heat exchanger tank,
it has a fresh water
cooling system. Raw
water is pulled
through the intake
and flows through
chambers in the heat exchanger and then discharged
overboard with the engine exhaust.
Check coolant level daily. The level in the coolant
recovery tank should be maintained at the “
F
ull Cold”
mark (1, Figure 6.6) when the engine is cold.
To avoid possible skin burns, the engine must
be turned “OFF” and cool enough so no heat
is registered on the temperature gauge. Only
after the engine is completely cooled is it safe
for you to remove the coolant reservoir cap to
check the level. Failure to follow procedure
may result in death or serious personal injury.
• Failure to maintain the coolant at the proper
level can cause engine damage. Your war-
ranty will not cover engine damage due to
overheating or any other cause associated
with improper coolant levels.
• Use only propylene glycol coolant. Use of
any other coolant or mixing coolant types
can cause engine damage. Damage to your
engine from use of any other type of coolant
is not covered by warranty.
• The coolant system should be flushed and
coolant replaced every two years. This
should be performed by a qualified Indmar
service technician.
