Indmar Marine Engines 6-11
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.
When adding coolant, add only Sierra brand propylene
glycol in an appropriate mixture with distilled water in
accordance with the directions on the container. Do not
overfill the tank. Do not mix anti-freeze types.
If the cooling system is completely empty, see your
Indmar dealer for assistance immediately to purge sys-
tem. Purging the system is a difficult procedure that is
not recommended for the boat owner.
Salt Water Operation
All Indmar Marine engines are capable of operating in
brackish or salt water environments as long as certain
precautions and maintenance procedures are followed.
Damage to the engine, both internal and external, that is
a result of inadequate maintenance on an engine used in
salt water will not be covered under the Indmar Limited
Warranty.
