CRUISING IN OTHER

CONDITIONS

CRUISING IN SALT WATER

After operating in salt water, wash out the
cooling-water passages with fresh water
to prevent them from becoming clogged-
up with salt deposits.

NOTE:

Refer to cooling system flushing instruc-
tions in “TRANSPORTING AND STORING
OUTBOARD MOTOR”.

CRUISING IN TURBID WATER

It is strongly recommended that the
optional chromium-plated water-pump kit
be installed if the outboard is to be used
in turbid (muddy) water conditions.
