IMPORTANT: MerCruiser recommends that propylene glycol (a
nontoxic and environmentally safe) antifreeze be used in the
seawater section of the cooling system for cold weather or ex-
tended storage. Make sure that the propylene glycol antifreeze
contains a rust inhibitor and is recommended for use in marine
engines. Be certain to follow the propylene glycol manufactur-
er’s recommendations.
a-Remove Hoses
b-Remove “T” Fitting
6 For additional assurance against freezing and rust, remove the
hoses from the “T” fitting of the thermostat cover and then re-
move the “T” fitting. Fill the engine seawater cooling system
through this opening with a mixture of antifreeze and tap water
mixed to manufacturer’s recommendation to protect engine to
the lowest temperature to which it will be exposed during cold
weather or extended storage. Clean the threads of the “T” fitting
and re-install into housing and re-connect hoses.
Perform all checks, inspections, lubrication, and fluid changes out-
lined in MAINTENANCE CHART under AT LEAST ONCE A YEAR.
