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 for Jabsco Installation



Mastercraft Piggyback Boat Ballast Bag Installation
One simple and completely reversible change is required to install the PiggyBack system, and the entire process takes less than 30 minutes.

Step 1: Loosen the hose clamps on the vent hose located on top of the hard tank and remove the hose. Try to unthread the barb vent fitting in the top of the hard tank. If this is removable use the 1” NPT fitting in it’s place.

NOTE: If the fitting is not removable use a short section of the black MasterCraft OEM hose and the gray 1” thread x 1” quick connect fitting between the hose extension and the tank barb.

Step 2: Connect the quick connect elbow fitting that is closest to the black 1 PSI check valve onto the ballast tank fitting seen above. Slide the red collar down to secure the connection.

Step 3: Loosen the clamp securing the hose to the thru-hull in the side of the boat and remove the hose.

Step 4: Using the pre fabricated kit place the hose that is not labeled onto the vent thru-hull fitting in the side of the boat. Secure with a hose clamp.

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.

Step 8: Locate the unlabeled, unterminated bare hose end and slide that onto the vent thru-hull fitting located on the side of the boat. Secure with a hose clamp.

Applications
This Piggyback system is designed to work with MasterCraft boats that have factory rear ballast tanks that are installed below the floor of the boat and use 1" hose connected to Jabsco Ballast Puppy pumps for filling and draining.
