OPERATION
80 eng
Operating in Saltwater or Polluted Water
We recommend that you flush the internal water passages of
your outboard 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 you keep your boat 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 propeller and gearcase with fresh water after each use. Each
month, spray Mercury Precision or Quicksilver Corrosion Guard
on external metal surfaces. Do not spray on corrosion control
anodes as this will reduce the effectiveness of the anodes.
Operating Outboard as an Auxiliary Engine
If the outboard is used as an auxiliary engine, stop the engine
and tilt the outboard out of the water when using the main power
source.
IMPORTANT: The outboard must be restrained from bouncing
while operating the boat using the main power source. Bouncing
can damage the outboard and boat transom.
Pre‑Starting Instructions
1. Connect the remote fuel line to the outboard. Make sure
connector is snapped into place.
