4. With sterndrive in normal operating position, open the water source completely.
5. Place the remote control in the neutral idle speed position and start engine.
NOTICE
Operating the engine out of the water at high speeds creates suction, which can collapse the water supply hose and overheat
the engine. Do not operate the engine above 1400 RPM out of the water and without sufficient cooling water supply.
6. Depress the throttle only button and slowly advance the throttle until the engine reaches 1300 RPM (± 100 RPM).
7. Observe the water temperature gauge to ensure that the engine is operating in the normal range.
8. Operate engine with sterndrive in neutral for about 10 minutes or until discharge water is clear.
9. Slowly return throttle to idle speed position.
10. Stop engine.
11. Shut off water and remove flushing attachment.
12. This step is only required if the boat is to be stored in the water. After the flush procedure is completed, remove the
seawater inlet hose from the thermostat housing and plug the hose to prevent water from siphoning into the boat. This
prevents seawater from contaminating the engine flush.
13. Tag the ignition switch with an appropriate tag requiring the seawater inlet hose to be reconnected prior to operating
engine.
Battery
Refer to specific instructions and warnings accompanying your battery. If this information is not available, observe the following
precautions when handling a battery.
!
WARNING
Recharging a weak battery in the boat, or using jumper cables and a booster battery to start the engine, can cause serious
injury or product damage from fire or explosion. Remove the battery from the boat and recharge in a ventilated area away
from sparks or flames.
!
WARNING
An operating or charging battery produces gas that can ignite and explode, spraying out sulfuric acid, which can cause
severe burns. Ventilate the area around the battery and wear protective equipment when handling or servicing batteries.
