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
drainage during the flushing procedures.
Keep water inlet pressure between 20 to 40 psi
(140 to 275 kPa).

Refer to
Propeller Hardware Installation
on
p. 67.
Place outboard in VERTICAL (DOWN) position in
a well ventilated area.
Remove plug and nozzle (overboard indicator)
from the flushing port.
Thread garden hose into flushing port.
Shift the outboard to NEUTRAL with the propeller
removed.
Turn water supply on.
START outboard. Run it at IDLE only.
Shut OFF the outboard. Turn off water supply and
remove garden hose.
Reinstall plug and nozzle. Position the plug and
nozzle to allow the water stream to be seen from

tion long enough for the powerhead to drain com-
pletely.
