2019 G23 is something wrong?

[hal2814]

I currently own a 230 and had the opportunity to ride in a friend’s 2019 G23 yesterday. He’s running stock with about 500lbs of lead midship. I get behind it and the surf wave is super disappointing. We ran 100% full on all ballast. I ran a few different speeds from 10.8 to 11.8. I ran NSS at 0 and 1. I ran NCRS from 3 to 5. I got push. I could go ropeless. But my 230 wave blows it out of the water with size and especially push. Like not even a personal preference thing. It’s a better wave. Some of my mutual friends had told me that before after riding both our boats but I really thought they were exaggerating or just being nice.

My boat is not a stock 230. I have 1,100lb bags in the rear and an under-bow piggyback up front, but it’s my understanding that should just put it neck and neck with the G23. Is there something different we should be doing? I didn’t think the 2016+ hull needed more weight. The only thing that occurred to me on the way home was that I didn’t personally see him fill the ballast. It was full by the time I got there. Could the boat show 100% full and be wrong maybe? The push felt like my 230 did the time my rear piggyback bags slid backwards and didn’t fill all the way.

Just looking for experience from people who have surfed both, especially a dialed in 230 and a stock G23. Is there something else we should be doing or some troubleshooting we should do? My plan was to eventually upgrade to G23 but now I’m spooked.

The ballast sensors can go bad. I have a GS20 and my sensors were reading 100% and when I opened up the floor there was nothing in them. I would fill them until you see the water coming out of the overflow to make sure they are full. You may have to re-calibrate the sensors using the dealer code.

The old sensors had issues with water intrusion in the connector. Nautique JUST released the new style of sensor that can be used that doesnt experience this issue. The linc will need a setting changed to account for the new style if sensor

I think I read on here if the boat is in river mode that will do it.

I have an update. Instead of looking at the sensors we filled it until water came out of the vents. The push still wasn’t quite there compared to my 230. The shape was great. And we were getting ok push in the 11.2mph range. But it trailed off further back in the wave. I had to pump in places where I could just lean on the 230. Then I brought out my bags. We started with 800lb bags in the rear and about 500-600lbs up front. The swim deck was underwater. That was too much. It was a washy mess am we couldn’t get up to speed well. Then we kept the weight up front and dropped 400lbs from each side in the back. The swim deck was touching water but not submerged. Bingo! That wave was amazing. I had push all the way back and it was a beautiful surf style wave at 11.8mph. I cracked a 360 without even picking up speed first. I remember the NSS was 0. I don’t remember the NCRS.

I know that a lot of people run mostly stock G23s and are totally happy with it. I’m glad that’s the case. But if you’re coming from a 230 and just aren’t getting the push you’re used to, you’re not alone. Maybe this will help you.

My 2019 G21 port ballast system always reads 100%. Very difficult to fill ballast tank.

Very common problem with Nautiques. Sounds like you have a faulty ballast sensor. When you get the dealer to replace it, I would replace all three of them at the same time.

If you just unplug the sensor you will be able to fill your tank without the computer cutting off the pump. Fill it once until you see it overflowing, empty it to 0%, and now your timer will take care of it and when you fill the next time the timer will stop the pump at (or very close to) 100%. That will help until you can have your dealer change the faulty sensor.

I was wondering if Nautique had gone to a timer system as I know several of the manufactures had determine the level of the ballast but didn't know if Nautique had taken that approach. Any liquid measurement device on a boat seems to be more of a suggestion than any kind of science. Between gas gauges that are far from linear to ballast gauges that never show full or empty these devices tend to be very hard to depend on. I occasionally boat on a great lake and would never think about going out without filling up before.
