Cooling System Flushing and Salt Water Maintenance
Flushing the cooling system with fresh water is necessary to neutralize the corroding effects of salt water or water
with impurities like silt, sand, alkali, and other particles as well as to flush out other residue left in the passages
of the watercraft cooling system.
Flush water passages when the watercraft is not going to be ridden again that day or if the watercraft is expected
to be stored for an extended time.
CAUTION:
Always follow the recommended flushing procedure below when flushing the watercraft cooling system to avoid
engine damage.
Never flush a hot engine. Severe engine damage could result.
Do not flush engine with engine turned off. Water will fill engine and severe engine damage may result.
WARNING
Do not touch any electrical part or driveshaft component when the engine is running. Severe personal injury or
death could result.
