1-1/4" thru hull
Solid build, ready to install, nice it has mpt.
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.

This thru-hull intake fitting is designed specifically for use below the waterline, and as such, has NPS threads extending from the flange almost to the end of the fitting. 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.

Something this simple doesn't need a lengthy review. It's solid brass so it won't corrode. It's NPT threaded so it works with anything you want to attach. It comes with a flare nut (others charge extra), though personally I always cut a backing plate to distribute the force over a larger area of the hull. I recommend using a high quality one inch hole saw, this will give you just enough clearance without taking away too much material. Thanks WakeMakers for great products with great support!
These mushroom thru hulls work very well. Follow the how to video on you tube and you should not have any problem. I used the 3M 4200 sealant on mine and was paranoid about possible leaks but when I got the boat in the water and tested it i was pleased to see there was not even a seep. Be sure to use the recommended size hole saw.
Added two of these to my custom ballast install. works great and matches factory equipment. will buy again
I'm adding another 1" thru-hull to my boat and purchsed the Bronze mushrooom thru-hull again. This is an excellent quality item, no issues, no leaks, easy to install. Wakemakers even provides a link to an easy to follow step by step instructions if you are unsure about drilling into your boat. I used the 3M 4000 adhesive sealer with it.
