Wake boat service- ballast pump winterize



Drain ballast bags as best as possible. There is typically water remaining in all bags/tanks. Fill with -100 degree antifreeze through outlet ports to stabilize pumps from freeze damage

Price per bag/tank. Ballast tanks, pumps, hoses and fittings must be properly winterized to prevent freezing damage during winter storage.

Because of the complexity of preparing a ballast system for winter storage, as well as the possibility of extreme damage to the ballast system if a preparation error is made, it is recommended to have a trained technician to perform all winterization procedures, including ballast winterization.

Winterization Process
1. Completely empty all ballast tanks and bags of any water that may be in the ballast system.
2. With all bags still hooked up to the system, identify the ballast thru-hull vents.
3. Add two gallons of -50 F RV type non toxic propylene glycol based antifreeze to each of the thru-hull vents. Colder climates may require antifreeze with a -100 F temperature rating. (A boat with 4 ballast tanks will require 8 gallons of antifreeze)
4. Once the antifreeze is in all ballast zones, use the manual ballast switches in the helm area to drain the antifreeze through the system. This will push antifreeze through the ballast system, across all pumps, hoses, fittings and intake valves.
5. Be cautious while using the ballast switches as antifreeze will be pumped out of the intakes mounted to the bottom of the boat. Once antifreeze begins to pump out of the boat through the 4 ballast intakes (three aft, one forward), turn the pumps off
