WakeBallast Bronze Mushroom Thru-Hull Intake

This bronze thru-hull water intake fitting is the foundation for an automated wakeboard ballast system. The intake of choice for a fully automated wakeboard ballast system, this mushroom style fitting will not force water through the pumps when running at speed, which means your bags won't fill unexpectedly, but offers an incredibly high volume of water so your pumps can fill at full speed, whether the boat is stationary or cruising across the lake. Available in a range of sizes depending on what type and number of pumps you'll be using, our mushroom intake supports up a mammoth 7,560 gallons/hour of water, making it more than sufficient for use with even the highest capacity wakeboard ballast pumps.

Those parallel threads make it possible to securely tighten the retaining ring during installation regardless of the hull thickness. Unlike other traditional thru-hull fittings that require the use of a bulky and expensive (not to mention overkill for ballast applications) sea-cock, our intakes are custom made to blend to NPT thread at the very end, making it simple to assemble our standard bronze ball valves onto the intake for connection to the rest of the ballast system. The flange is contoured to accept a bead of marine adhesive for a water-tight seal, and is drawn tight against the outside of the hull by the tightening of the included retaining nut snug against the bilge surface.
