MAINTENANCE
© 2016 Indmar Marine Engines
If the cooling system is completely empty, see your
Indmar dealer for assistance immediately to purge
system. Purging the system is a difficult procedure that
is not recommended for the boat owner.
Salt and Hard Water Operation
All Indmar Marine engines are capable of operating in
brackish or salt water as well as in hard water or water
with high mineral content as long as certain precautions
and maintenance procedures are followed. Your dealer
will be aware if the local freshwater lakes in your area
will require any special precautions to keep your engine
functioning properly. Damage to the engine, both internal
and external, that is a result of inadequate salt or hard
water maintenance will not be covered under the Indmar
Limited Warranty.
External Care
Your engine has been carefully primed and painted to
protect it against rust and corrosion. To keep your engine
looking like new, Indmar recommends applying an
anti-corrosion compound. Regular application (every 3
months) of this protectant, particularly on exposed metal
surfaces, motor mounts and electrical connections, will
displace water and seal the surfaces against penetration
by corrosive agents. Rinsing the engine with fresh water
between applications of the protectant will further protect
the exposed surfaces.
INTERNAL (COOLING SYSTEM) CARE
Fresh Water Cooling – Half Systems
A fresh water cooling system that uses anti-freeze in the
engine but raw water in the exhaust manifolds is referred
to as a half-system. Although the engine is protected,
it is still important to flush the engine with fresh water
to remove as much salt water as possible from the
raw water side of the cooling system as well as from
the exhaust manifolds and risers. For more convenient
flushing, ask your dealer about permanently installing a
flushing device that allows easy connection of a water
hose.
FRESH WATER COOLING
All fresh water cooling systems, must be inspected and
maintained annually, usually during winterization.
