If the boat cannot be removed from the water during freezing temperatures, the
outboard should be left in the full down position.
Operating in Saltwater or Polluted Water
It is recommended that the internal water passages of the outboard are flushed
with fresh water after each use in salt or polluted water. This will prevent a
buildup of deposits from clogging the water passages. Refer to Maintenance ‑
Flushing the Cooling System.
If the boat is kept moored in the water, always tilt the outboard so the gearcase
is completely out of water (except in freezing temperatures) when not in use.
Wash the outboard exterior and flush out the exhaust outlet of the propellers
and gearcase with fresh water after each use. Each month, spray Mercury or
Quicksilver Corrosion Guard on external metal surfaces. Do not spray on
corrosion control anodes as this will reduce the effectiveness of the anodes.

IMPORTANT: Do not rinse the cowls with water when the outboard is in a tilted
position, as this could allow water to enter the air intakes on the rear of the
upper cowl. Always lower the outboard to a vertical position prior to rinsing the
cowls.
Operating at High Elevations
Your engine automatically compensates for high elevation changes. A different
propeller pitch may help reduce some normal performance loss resulting from
reduced oxygen in the air. Be sure to change propellers as a matched set.
Consult your dealer for assistance.
