3. Attach the water hose (generally hot 140-degree water) to the
flush fitting on the Strainer Pro or other permanently mounted
flushing device.
4. Turn on the hot water supply to the hose between 1/4 and
1/2 pressure. Hot water will exit the boat through the thru-hull
fitting in the bottom of the boat. This will ensure that the water
inlet hose and thru-hull pickup have been decontaminated.
Continue flushing per the instructions in your area (generally
two to three minutes).
5. After the appropriate flushing time, turn off the hot water
supply.
6. Place the shut-off valve (sea cock) in the boat to the CLOSED
or OFF position to force all of the water through the engine/
drive train.
7. Turn on the hot water supply to between 1/4 and 1/2 pressure.
Start engine and let it run at idle with the transmission in
neutral.
8. Turn water supply to full pressure.
9. Let the engine run until the temperature indicator in the boat
or the temperature of the water exiting the exhaust outlet
reaches the designated temperature (usually 140°F). Once
temperature is attained, let the engine run for the designated
time (generally two to three minutes). NOTE:
engine up to 1200 RPM to speed the warm-up process.
10. Reduce water supply pressure to 1/4 to 1/2 pressure.
11. Turn engine off.
12. Turn water supply off.
13. Remove water supply hose from the Strainer Pro or other
flushing device and replace the flush protection plug.
14. If the boat is equipped with a shut-off valve (sea cock), place it
in the OPEN or ON position.
