The Gravity Ballast system utilizes a manifold and a solenoid valve to independently fill each bag or tank. The solenoid valves have a small toggle switch that can manually override the opening of the valve. The manual toggle switch needs to be in the “down” position to allow the system to be controlled by the switches in the dash area. If the manual toggle switch is turned to the “up” position, the valve will be open all the time and cannot be controlled by switches in the dash area. If the ballast system fills continuously while running the boat, check to make sure the manual override toggle switch is in the “down” position. If it continues to fill and the manual toggle switch is in the “down” position, check for debris that may have clogged the solenoid valve forcing the valve to stay open. If the valves continue to fill, closing the manual emergency shut-off valve will prevent any water from entering the system.

Each Gravity Ballast system also includes an in-line water strainer before the manifold. This strainer will keep debris out of the solenoid valve and should prevent the valve from getting clogged up and forced open. The strainer cover should be removed periodically and the filter screen cleaned to prevent debris buildup on the mesh screen. Be careful when removing the cover not to lose the O-ring used to seal the cover. Also, the strainer should be

removed and drained during winterization.

To fill the ballast system, press the fill switch. To empty, press the empty switch. With the ballast full, the boat may porpoise at speeds above 25 mph.

Empty ballast before trailering the boat. DO NOT trailer boat with ballast full!
