Flushing the cooling system

Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:
● Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.
●
Do not run the engine for more
15 seconds without supplying water,
otherwise the engine may overheat.
