WakeMAKERS Mastercraft PiggyBack Rear Factory Ballast Upgrade
The Rear PiggyBack Ballast System Kit is designed to make use of the existing pumps, hoses and switches in your Mastercraft, to expand the capacity of your factory rear ballast tanks. This kit includes everything needed for the installation, including a ballast bag of your choice (Fly High, Straight Line, or Eight.3) and the necessary quick connect fittings.
NOTE: Any 2007 MasterCraft will require the installation of a new Jabsco AI Timer Module due to the inability for the timers to be increased above 6 minutes. All 2008-2011 MasterCraft boats will require timer reprogramming to increase the fill and drain times and can be increased to a maximum of 20 minutes, Download Instructions.
One simple and completely reversible change is required to install the PiggyBack system, and the entire process takes less than 30 minutes.

Step 5: Thread the male quick connect fittings into your MasterCraft Ballast bag.
Step 6: Connect the straight hose fitting, labeled Fill/Drain, onto the bottom bag fitting. Slide the red collar down to secure the connection.
Step 7: Connect the elbow hose fitting, labeled Vent/Overflow, onto the top bag fitting. Slide the red collar down to secure the connection.
