Cooling System
Check the condition of cooling system compo-
nents regularly:
• water intake screens
• water pump
• all internal water passages
• thermostats
• all external water hoses and fittings
• vapor separator cooling passages and fittings
• EMM cooling passages and fittings
• overboard water pressure indicator.
Water Intake Screens
Inspect condition of water intake screens. Clean
or replace as needed.
Confirm function of overboard water pressure indi-
cator.
Engine Flushing
Flush the outboard with fresh water following each
use in brackish, salt, or polluted water to minimize
the accumulation of scale and silt deposits in cool-
ing system passages.
The outboard can be flushed on the trailer or at
dockside; running or not running.
IMPORTANT: The outboard must be located in a
well ventilated area with appropriate ground drain-
age during the flushing procedures.
Keep water inlet pressure between 20 to 40 psi
(140 to 275 kPa).
