Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt. In addi-
tion, fogging/lubricating of the engine is
mandatory to prevent excessive engine
damage due to rust. Perform the flush-
ing and fogging at the same time.
WARNING
EWM00090
●
Do not touch or remove electrical parts
when starting or during operation.
●
Keep hands, hair, and clothes away
from the flywheel and other rotating
parts while the engine is running.
NOTE:
●
When using the flushing attachment,
maintain adequate water pressure and a
steady water flow.
●
If the overheat warning device is activated,
turn the engine off, and consult your
Yamaha dealer.
6.
Run the engine at a fast idle for a few
minutes in neutral position while supply-
ing fresh water.

ly spray “Yamaha Stor-Rite Engine
Fogging Oil” (Part No. LUB-STRRT-12-
00) alternately into the intake silencer or
the fogging hole of the silencer cover, if
equipped. When properly done, the en-
gine will smoke excessively and almost
stall.

wipe off any excess water.
