normal operating temperature to ensure proper flushing.
7. Reduce the engine speed to idle, shut off the engine and
immediately shut off the water supply hose. Please note, failure
to shut off the water supply hose immediately could possibly
result in engine damage.

step 1 ball valve.

securely.
Battery Maintenance
Take care when connecting or disconnecting a battery charger. Be
sure the charger is turned off and unplugged from power source
when you clip on/off the connecting clamps.
Make sure you have a solid connection with the charging clamps.
Poor connections are common causes of electrical arcs and engine
problems. Follow instructions.
Explosion or fire hazard from vented
fumes can cause death or serious injury.
• Wear eye protection and rubber gloves when working
on or around batteries.
• DO NOT charge or use a battery booster to start your
engine.
• Charge the battery outside of the boat.
• DO NOT smoke or bring a flame near a battery at any
time.
• DO NOT have your head directly above a battery when
making or breaking electrical connections.
• DO NOT use a metal object to spark between battery
posts to check if the battery is charged.
