WakeBallast Preassembled Bow Bag Double Decker Hose Kit

WakeBallast Bow Bag Vent Kit fixes a problem most boat owners don't know they have: if your bow bag never fully fills or feels lighter than expected, trapped air is usually why. This kit gives your bow bag a dedicated vent connection to your factory ballast system — no drilling, no permanent mods. Air trapped from towing or sitting on a lift can hide as much as 200 lbs of "ballast" that's actually just air. This kit vents it out during fill, so your bag actually holds what it's rated for.

Compatibility

Built for tow boats with a center locker ballast bag that vents out the side of the boat.

What's in the box

Everything you need, pre-assembled. Thread the included fitting into your factory ballast bag, disconnect the factory drain line from the thru-hull, and reconnect it to the supplied tee fitting. About 15 minutes, start to finish. You need to select the hose size needed. If you're unsure this kit should match the size of hose used to vent your center locker ballast bag, and the size of the thru hull barb nub where the center locker ballast bag currently vents through. 

How it works

The kit taps into your center locker's vent line to fill the bow bag. Once the bow bag is full, the included secondary hose connects the port on top of the bow bag back to the existing thru-hull vent — fully integrated with your factory setup.

Fully reversible

No permanent changes to the boat. Revert to stock anytime — though once you've got the extra ballast, you won't want to.

Frequently Asked Questions

Do I need to drill any holes to install this?

No. The kit connects to your existing factory ballast lines — no drilling required.

How long does installation take?

About 15 minutes.

Why would my bow bag not be filling all the way?

Air gets trapped in the bag from towing, trailering, or sitting on a boat lift. Without a proper vent, that air stays in the bag and takes up space water should fill — sometimes as much as 200 lbs worth. This kit vents that air out during fill.

Will this work with my boat?

Yes, if your boat has a center locker ballast bag that currently vents out the side of the boat. That's the setup this kit is designed to integrate with.

Can I go back to my factory setup if I don't like it?

Yes. Installation is fully reversible and makes no permanent modifications to your boat.
