NXT 20 Added Ballast

If all goes well, I will be the owner of a NXT 20 later this week. I called Wakemakers and they indicated that they do not have an upgrade kit at this time, and do to the aerator style pumps, it adds another twist? What have others done for integrated ballast upgrades on the NXT? What size sacs will fit in the rear lockers and will the X2 bow sac fit under the front bow seating? Is it wrong to assume that you could tap into the overflow line with the sac and take the top line of the sac into the side overflow?

I fit a 540lb bag in the locker no problem. I think you can go up to a 700-800lb bag, it just may not fill quite all the way. Currently I fill them with a tsunami pump over the side but was looking to get it integrated.

The issue with the aerator style pumps is back pressure. Once you piggy back the bag on top of the tanks the back pressure will force the bag to leak back out the empty pump. You're kinda stuck with only two options, as an automatic solenoid/sprinkler valve in line w empty pump, or add a manual gate/ball valve to the empty line. The fill pump should have a factory installed flap/check valve on the line. If it doesn't you'll need to add one there too.

I gotta be honest I didn't even look to see what pumps the NXT's were running, but using an aerator sytem is not something I would have pegged MC to cut a corner on. It makes piggy backing/ adding additional ballast way more difficult and cumbersome.

I have 400's in the rear lockers integrated so they fill and empty with the switches just adding the bag to the overflow of the hard tanks.

I am going to upgrade to 600's in the rear and use a 500 lb bow bag sitting on the front seats using an external pump when needed. the storage under the bow is split up with supports so wont accept a full bag.

Pulled the trigger and have the NXT in the garage to begin the ballast upgrade. In the rear, it looks like a tapered bag wold fit best due to the "waterfall"design of the transom. Which sacs are those that have posted using specifically? Additionally, what is the optimal surf set up for the NXT with the surf system? For surfing, does it like added bow weight, if so, how much and do you fill both port and starboard and use the Surf plates or does it respond better to only the surf side being weighted? I'm trying to get as much done while she is in the garage before I take her to the marina.

Congratulations on your new boat. We took delivery of a new 2015 NXT20 last month. The dealer added larger than stock bags last summer, to improve the surfwake (which is impressive). It is plumbed to use the stock pumps via hard tank overflow. I recall them telling me the rear bags are 750lbs each. When we took delivery I noticed that once the main tank was full there was a fair amount of water coming out of the overflow. So, I asked the service manager to check it out. He changed the plumbing to mirror the was the 2016 is set up with check valves and such, although he did share that the hard tank in a '16 is different. Have not had a chance to surf it yet, waiting for a little warmer air temperature to contrast the water Temps in the low 60's.
