FatSac C1062 Yamaha Jet Boat 19ft Custom 650 lb Ballast Bag with Fittings

The FatSac C1062 is a custom-fit ballast bag engineered specifically for 19-foot Yamaha Jet Boats, adding a full 650 lbs of ballast to the rear swim platform to help create a surfable wake. Designed to sit securely on the swim deck step, this bag gives Yamaha owners a straightforward way to get into wakesurfing without permanent modifications.

Key Features:

• 650 lb ballast capacity — delivers serious weight for improved wake shape and wakesurf performance
• Custom fit — sized at 35" L × 30" W × 26" H to match the 19' Yamaha swim platform
• All fittings included — comes with W730, W731 (×2), and W749 valves/caps ready to use out of the box
• Compatible with W709-SUPA Supa Tsunami Pump for fast, efficient filling and draining
• 4 welded-on PVC cleats — provide secure anchor points for tie-down ropes (rope not included)
• Dedicated fill/vent port and drain port for controlled water management

Important Usage Notes:

• Always pre-inflate the bag with air to establish proper positioning and tie-downs before filling with water
• Secure the bag through the cleats on both the top and bottom using a 12' or longer rope — handles are guides only and are not load-bearing
• The bag must be filled 100% full; partial fills can cause the bag to shift and may result in damage or warranty void
• Use the air release valve at the top to bleed air while filling with water until the bag is completely full

The FatSac C1062 ballast bag is sold individually and includes all necessary valves and caps. A compatible pump (W709-SUPA) and dock line (M1028) are recommended but sold separately.
