    Default G23 NSS Review

    Got to spend about an hour out on a 450 G23 demo and try out the NSS. water was still too cold and there were 20-30mph winds. up front, I am a surf snob coming from a 247. I have surfed behind Malibu's surfgate, so I am familiar with what its capable of and its limitations. I was very impressed with the NSS. Worked exactly as advertised, shows great potential, will be very interesting to see what the Nautiques do with 750s and 1100s in the trunks. you do have to countersteer some against the deployed side when you deploy it...nothing crazy or unreasonable. minimal bow rise, didn't even need the bolster. Not exactly sure what SURF VERT 0 vs SURF VERT 5 is...unless its the length of the deployed gate beneath the water. Surf Vert 0 yielded best results. The pic below is 11.6mph, both rear tanks full, front about 60% so about 2400lbs total ballast. gas tank was 1/8th, 3 men, otherwise empty unloaded boat. NCRS at 5, Surf Vert 0. it looked about the same on both sides. I think we are going to see best results with approx 60/40 weighting to your preferred side. You def can run it perfectly even and switch back an forth... but a slight cheat on weight to one side made a huge difference.

    Looks pretty good. ESP with low fuel. My 230 wave was much larger w full fuel. And it loved added weight.

    Thanks for the review. How does it compare to the surf gate in the little you got to see it.

    BTW, Ryan, I knew I recognized your screen name from somewhere. I am also on YJB and am upgrading from the 212x to the SANTE 210.

    Nice! I too am coming from a 247 and have a G23 on order. In your opinion how did the G surf wake compare to the 247 at least visually? Also did you play with the settings to adjust the length of the wave? I'm a big guy at 205 so I'm wanting to make sure it has good push for surfing.

    Btw, any other pics of the boat? I see the interior accent is yellow, I'd love to see more pics!

    I think NSS is going to be better than Malibu's surfgate. Reason is, the gate technology is limited by how much you sac it out. At a certain point, you sac too much, water will start coming over the tops of the gates and it's downhill from there.

    NSS doesn't have that problem with it extending out FROM the boat.... Initial stab I'd say your limiting factors will either be the swim platform dragging if you sac too much... Or horsepower/cavitation to get 10k+ lbs up to 12mph. G23s come with the acme 2323 which is good... But I think the 2315 would have been better for the 15" 1235 stump puller equivalent.

    What I was looking to confirm is that with stock ballast you have a long well shaped wave. Just from that pic above I could tell you that you easily have a 15+ft rideable wave on stock ballast. We are going to have some serious waves coming off these boats... For not being designed solely as a surf boat.

    Only other critique I'd share would be fill/drain time on the factory ballast. $130k premier wakeboat... Throw a second pump on each tank..... first for no fail redundancy... and also get the fill and drain times under 4min. That would add about $1k to the price of the boat.

    Good review, thanks for sharing. Just an FYI that the G's w/ the ZR450 come from the factory with the Acme 2313, which is a 15". I ran the 2315 on mine last summer. Both are 15"x12" props, the difference is in the cup: 2313 has .150 and the 2315 has .105. You'll experience a little better hole shot when heavily weighted with the 2315, and run about 200 more rpms.

    Don't know exact... But Seemed long, need someone else to chime in with exacts. 8-10mins maybe? It's the Jabsco reversibles x3, 1 per tank. I believe it was 1" hose. They fill and drain out thru the same holes in the bilge, so the only peeing you see is if you overfill the tanks. Good solid setup, but you are at no faster than idle boat speeds on draining due to pump pushing/draining water out and lake water pushing in i would believe. Anyone just push thru that and motor home fast while draining? Reciprocal should apply: faster fill times I you are up on plane?

    Iron, yes, thanks for the catch. Yes it's a 2313.
