Flushing Cooling System and Fogging
Engine
Cooling system flushing is essential to
prevent the cooling system from clogging
up with salt, sand, or dirt. In addition, fog-
ging of the engine is mandatory to pre-
vent expensive engine damage due to
rust. Perform the flushing and fogging at
the same time.
1) Remove the top cowling and silencer
cover. Remove the propeller.
2) Install a flushing attachment to the
lower unit. (Flushing attachment
available from your Yamaha dealer).
cC
Avoid running the outboard at high
speed while on the flushing attachment,
or overheating could occur.

8 Do not touch or remove electrical parts
when starting or during operation.
8 Keep hands, hair and clothes away
from flywheel and other rotating parts
while engine is running.
3) Run the engine at a fast idle for 10~15
minutes.
4) Just prior to turning off the engine,
quickly spray “Yamaha Stor-Rite
Engine Fogging Oil” (Part No. LUB-
STRRT-12-00) alternately into each
carburetor. When properly done, the
engine will smoke excessively and
almost stall.
5) Remove the flushing attachment and
wipe off any excess water.
6) Install the silencer cover and top
cowling. Install the propeller.
