Insane Value Wakeballast 2015-2020 Nautique G25 Rear Factory Double Decker Upgrade - Limited Release [gkD6fAxU]

Details: MADE TO ORDER WHEN ORDERED, EXPECT 2 WEEKS TO SHIP

This WakeBallast Double Decker upgrade integrates into the hard tanks below your rear lockers to increase the overall capacity of your factory ballast system and produce a bigger wake.

Our aftermarket ballast solutions increase the overall capacity of your boat's factory ballast system for improved performance while keeping the convenience of controlling all ballast with the switches at your dash. This is integrated into your boat's existing ballast system for automated filling/draining.

These Double Decker ballast bags in this kit that are placed in the rear lockers on top of the factory hard tanks. The additional ballast bags are integrated into the rear factory ballast tanks for an automated fill/drain process using the existing pumps, hoses, and switches. Once the factory hard tanks are full, excess water flows into the WakeBallast ballast bag and begins to fill it. Once the additional ballast bag is full (which means the factory hard tank is full), excess water flows out of the bag's overflow line and through the factory thru-hull fittings, allowing the system to function exactly the same as the stock setup. Draining is exactly the opposite; as the factory drain pump removes water from the hard tank, gravity forces water out of the WakeBallast bag and into the hard tank until both the tank and bag are empty. 

The rear lockers of the boat is the most important spot for additional weight, helping to increase the size of your Nautique's wake. Depending on the year and model Nautique you have, this will increase the capacity of your ballast system from 250 lbs to 1,700 lbs per side! 

This user-friendly system can be a DIY install that can be completed in your garage over the course of an afternoon. Don't want to do a self-install and would rather take your boat to a professional? Talk to your boat servicer about installing for you.

What's Included:

  • Port Snug fit 1,345lb Ballast Bag
  • Starboard Snug fit 1,345lb Ballast Bag
  • All required pre-assembled fittings and connectors required for installation
