Possible new Nautique owner, need HELP!!!

[Bottlefedsi]

Hello everyone, my name is Sean and I am currently an Axis owner looking to upgrade. The boats I am interested in are the 17 MXZ 22 and the 17 G21, has anyone ever compared the 2 boats on the water, I have a great relationship with my local Malibu dealer so I have driven the MXZ quite extensively. I havent had a chance yet to get a G out on the water but in about 2 weeks I will. I was just hoping someone could give me some great info on the G other than the obvious that the dealer has already done. FYI, we pretty much only surf with a 4-7 person crew 8 being tops on a very limited basis. Thanks in advance.

Sean, any adversion to a G23?

[sgresham]

This might not help, as I do not have direct information regarding the G21, but I do have knowledge between Malibus and Surfgate and the NSS and NCRS system. My first boat was an Axis A22, and I moved from that Axis to a Nautique G25. At the time I had my Axis, I was mainly interested in wake boarding, and the Axis handled that task well. I also bought the G because I wanted to wakeboard mostly, and wake surf a bit. Well, even though the Gs are phenomenal wake boarding tow boats, I have moved to almost strictly surfing, and the G handles this task extremely well. I also have a buddy who has a Malibu M235, and I would choose the Nautique Wave over the Malibu wave any day of the week. The Malibu wave has a ton of push for sure, but, in my opinion, the lip isn't very aggressive at all, and the wave is just boring to me. I am actually about to trade my 25 in for a G23, and anytime a person is thinking about trading, other boats always creep into the mind. I have demoed an MXZ 24, a Mastercraft X23, and so far nothing has made me say, "Wow, I want that wave." I'm always searching for the best, but so far it seems that I already have it with a G boat.

As far as the G21 is concerned, I have no doubt that it will throw an awesome wakeboard wake and surf wave.

Thanks for the info guys, I dont have a huge crew with us all the time so the Nautique guy said the G23, being bigger, needed more people to sink it in order to produce almost exact surf wave as G21, so he recommended the G21.

Also, do you think the H5 is good enough for the G21 or is the H6 a better option when fully loaded down with ballast? The sales guy said they produce the same torque ruffly so going the H6 was a waste of money. I found that hard to believe as Malibu is begging me to do the 450 in the MXZ rather than the 410.

[NautiqueJeff]

5.3L H5 - 355 HP, 405 ft/lb
6.2L H6 - 450 HP, 465 ft/lb
6.2L Supercharged XR7/XS7 - 550 HP, 545 ft/lb

I have been in a fully-loaded G21 with an H5, and it did fine, but the H6 is certainly better. Keep in mind that the H5 is not even offered in the G23 anymore.

Also, keep in mind that those torque numbers are straight from the engine, before the 2:1 v-drive, which basically doubles the torque at the prop. I am not sure what gear ratio the Malibu uses, but I don't think it is 2:1, so that is likely an advantage for Nautique, at least as far as torque at the prop goes.

Now, if you're really mainly just surfing, the H5 in a G21 will be fine for you. I drove for a surf camp last summer in a G23 with an H5, and it was fine for surfing. Wakeboarding with full ballast and a full boat with an H5 in a G23 doesn't provide the same experience.

I would argue your dealer gave you some bad info. Add in plug and play on either the 21 or the 23 and the G23 still wins out in surf. The old days of having to completely sink the bias with ballast and lean it over crazy are of the past. If you have the room and the tow rig for the G23 I would do that in a heart beat . I can't give a direct comparison of the 21 to the mxZ because I haven't been in the 22 MXZ ever.

I have a 2016 g21 w h5. Power seems really good and it's great on gas. I did tons of research before I bought. The g21 is an interesting boat however when it comes to the surf settings, the best surf wave is achieved by leaving the front ballast empty or near empty, and filling both rear ballasts full. Then depending on your crew, (if it's onl like 3-4 people on board) add approx 300lbs bag to port rear locker to offset prop rotation. And that's it. In other words, if you go out on a demo and the dealer uses the factory surf setting on G21, it won't be that great. Convince dealer on g21 demo to try what I mentioned. It is scientific fact that the g21 hull is easier to sink than the g23 and 25, but it gets weird. G21 owners have tried additional bags, lead, full factory ballast f+r, etc, on the G21 and my research dug up that no one got a better wave on the g21 than the aforementioned settings. Guys were shocked when they emptied out their front ballast and the wave got better. Weird right? Extra weight didn't equal better wave. So the H5 is an outstanding choice because you're not gonna want to add 2000lbs of extra ballast to get a better wave on the G21.

Now the G23, you're gonna want to add bags and or lead and its gonna get heavy. H6 for sure and thats all Nautique offers now so that solidifies that choice. On the test drive, the factory surf settings will be pretty good, definitely better than the factory setting on the G21. But now the upgraded engine and larger boat you're talking $30k more than a G21. If you go used and get a pre-2016 you'd want the 450 or 550 only IMO,

My buddy has a 2016 G25 and uses full factory ballast plus like 2500 more pounds of lead and bags to sink that monster. He accepts no less engine than the 550, anything less and his 12,000 pound boat won't perform. That makes sense when you think about it, his G25 is like 4000 lbs heavier than my G21 on the water!

So to sum it up simply in my opinion: g21 h5 is perfect, g23 h6 is perfect, g25 supercharged 550. Hope that helps!

Also, have you contacted Miguel at Miami nautique? He's a good guy. He always has boats he's wheeling and dealing with from rich clients that upgrade every year. I didn't end up buying through him but my friend did and he was great.

Hi
I've read your quote about the g21 with full rear ballast. I have tried many settings and I tended to choose ballast in the front to make the wave longer. If not it looked loke a short masivve wall...
I' ve got a question. With your setting what speed do you set? Is tje wave long enough?



G21 2014 with 409 engine. Today the temp raised to 100 and switched off. Restarted after cooling down and raised again so stopped and checked cooling circuit.
Intake filter clean. Heat exchanger clean. Antocooling just a bit low but nothing worrying? Thermostat looks ok although no water came out when I removed it.
Finally removed the impeller and it was destroyed.
I changed it in May and I' ve done less than 100h since then.
My worry and question are....
1. Why?
2. Do you think the impeller destroy is the cause or the consequence of something else?

That's the biggest issue with the G21, wave is short. I'm going to experiment more when it warms up, but next time you go out try NSS 3, NCRS 3, 11.3 MPH, both rear ballasts full, front empty. Sit a couple of guys on the surf side rear. The other half of your post should be reposted in a new thread.

How is the Bow rise when the front ballast is completely empty? The MXZ full to max with the surf setting on full vert, seat all the way up, still hard to see over bow.

I would seriously consider the G23 over the G21.... that extra 2' is quite noticeable in my opinion. The cooler in the floor is also a nice convenience on top of that. Resale on a G21I believe to be better as well plus a 23' boat is by far the #1 selling boat in the industry. Even with a smaller crew size the G23 would be much more comfortable if is within your budget...

Hi Jakehere, how is the surf wake on your buddies G25 when fully loaded compared to your G21?

G25 is better, but not $50k better. Tons of pros shred a G21 way better than I ever could hope to.

Also the G21 is really 21.5' so it's a foot and a half shorter than the G23, (12" in the middle and 6" at the bow.) To me it wasn't worth $25k more to go up to a new G23 at the dealer. I don't take out a group any larger than 8 people. Maybe 10 max and G21 is great.
