G23 450 NSS Review

[nyryan2001]

Pbolt- yep the rollers this produces are massive. I took a set the of rollers broadside and it pitched so violently 3-4 times the wave top was easily at the rubrail by the side windshield on the 3rd pitch with the boat leaned in hard from the previous pitch. FYI no lake houses on my lake, and we are generally respectful of others not to swamp their boats.

Now, the good thing is there was little to no worry about taking a wave over the bow like the Malibus do. Even with the extra weight 7-900lbs not so much a problem with the G23. Now, coming off the throttle fast with a lot of ballast you WILL take a wave over the transom every time. Come off on a reasonable pull to neutral and it won't happen.

How bad is the exhaust with the 450 as compared to the 550 when surfing? Debating which engine to decide on. I have always liked more power in the boats I have owned, especially with the 550 causing the RPMs to be less than in the 450 (from what I have heard). But it makes no sense if I keel over from exhaust inhalation while surfing. Is there a large difference using the 450 v 550 in power? the time to get on plane? I plan to wakeboard with the standard ballast, and only use an 1100 in the surfside locker while surfing. Any advice would be much appreciated.

I have driven/ridden both the 450 and the 550. I can't comment on the exhaust, but with stock ballast there was a huge difference between the 450 and the 550 with regard to hole shot. Also, it felt like the 450 bogged in tight turns. I didn't experience this with the 550 (which drove more like a sport boat). After comparing, there was no question as to which one I was going to get. The 550 now comes in a less financially painful version too. (without the shiny headers and closed cooling).

I'm guessing even bigger delta in peak torque and more useable torque down low in rpm range that makes a difference

How's the testing going?

FINALLY just got my 2315 yesterday.... just need to get out on the water. Weather forecast isnt too entirely favorable. If the 2315 isnt giving me what I am looking for then it will be the 2419. HAS ANYONE USED THE 2419 yet???? THATS the final monster torque prop out there, was hoping someone had used it. really inetrested to see that that .075 cup performs on our boats.

Ive put about another 8hrs in surfing over the last 2 weekends on the 2313. Long story short, I am loving the boat more and more. Very very capable surfboat, loads of potential. Folks saying the G's arent ideal for surfing dont know what they are talking about and havent taken the time or dont know how to dial a boat in. In the next week or so I will post more pics... MUCH improved over the 1st set i posted.

couple observations:

Allegations of being a gas hog. the 450 isnt anymore of a gas hog than any of the other comparable engines. I came from the 6.0L 400hp Indmar.... its about the same. Plenty of power in the 450 for 98% of folks. if folks cant get the weight up is likely due to a ridiculuous prop shaft angle too much weight in the back vs lack of power.

LEFT turns at slow idle speeds are certainly into the barge like category with the G23, I assume from the direction of the prop rotation. I came from a big boat... so I know barge driving... turn radius left is kinda bad, especially in tight areas in marinas, docks etc. right turns on the otherhand are super tight. I use this alot when surfing.... when the surfer falls, slow down and HARD right turn at idle speeds inside my own wake radius so i dont even go over my own rollers as they spread out. That hard right turn as you come down off plane is the key, only to the right with the G23, no way for left. I love not having to worry about taking waves over the bow as much like in the Malibu.

There is an electrical interference problem between the NSS/Jabscos and the stereo--- when the NSS deploys, or pumps cycle on/off, only sometimes you get noise (pop crackle) thru the system. As expected, running boat stereo systems thru the Perko vs an isolated dedicated run off the Batteries will lead to noise. I need to make that change at some point, prob at the same time I do my overall stereo upgrade.

Fold over center winshield foam, wrong choice of material. compresses too much and causes a metal on metal rub on the driver's side and scraped off the powder coat, will have to be warrantied.

Gotta do something to find the vibration sound while engine idles around the engine... i think its those slide in dividers on either side of the engine sitting loosely in their tracks.

Why is it you can control an Iphone from port USB but not Starboard at driver's dash? oversight?

My 70% setup(how I will likely run 70% of the time ie surfing 1.5-2hrs at a time) stock factory ballast, +1100 in the surfside trunk. 3-5 passengers sit where ever, doesnt matter. Slight lean to the surdside. GREAT quick setup here and not too long to wait. This gives you a 15ft long, roughly waist high in the middle (I'm 6'1")... very very steep and fast, tons of push. We run 11.6 -12mph. what a blast. engine runs 3200-3400rpms on the OEM 2313. Low gas--> ie less the 1/2 tank actually makes the wave better as it throws the bow up higher gouging the water in the back... but worse prop shaft angle and higher RPMs.

My 30% setup(when we are froggy and will be out for a while >2hrs) stock ballast, 1100 surfside trunk, maybe 400 in the other trunk and 1100 in the bow. This will give you a 15-20ft wave that is pro-level quality. I will share more pics here and some Go Pro video. Lots of weight here, will likely be best with the 2315 or 2419 vs OEM 2313.

Awesome, thanks for sharing. Can't wait to see pics and video.

Man I was really hoping to get away from having additional ballast! (my delivery is early June) What does the wake look/ride like with OEM only? Having to cheat to one side with additional ballast really negates the ability to switch quickly from righty to lefty riders.

[nyryan2001]

WakeSlasher-

OK, I dont want to misrepresent....Stock ballast alone will be GREAT for beginers and intermediates. I had my 8yo boy ropeless port side this weekend, what a blast. It truly is ropeless rideable off stock ballast alone for just about anyone, just dont expecte 15ft of rideable pocket. Understand I am a surf snot and I like the fast 11.6mph+ waist/thigh high perfect form 15-20ft barreling wave. I bought the G23 to SURF monster waves. getting there.


I do the slight cheat to one side because I am after that pro-level wave. Definitely NOT required. Board selection will be key for stock ballast only surfing... the faster the board the most rideable length you'll get.

[wakeslasher69]

Cool thx! Most of my riders will be beginner to intermediate, but there are a few of us that are a bit higher level so thats good info to have. Since it will be awhile before I get to play with my G23, I figured I'd ask you; how much does the Vert and NCRS affect the surf wave?

[AllianceBJJ]

So I assume that the exhaust is still an issue? My G23 (and every other I have personally seen) seems to have a crazy amount of exhaust release.

We have avoided surfing so far, since we only surf port side, due to what looks to be a lot of exhaust.

I have also noticed that mine runs a bit rough around idle and has actually cut out a few times in that 0-5mph range. Buxton has said that they have had some others with this too....

[iamcdn]

I think there is a group buy for FAE on tigeowners if anyone is interested.

[ers906]

If I understand correctly, the NCRS is not the same as the NSS? Do you have the NSS on your boat yet? I am wondering if that will let you use a bit less weight (at least in the bow). I am hoping to be able to keep the amount of exposed ballast to a minimum. In the lockers I will be using the new Ronix bags and pumps. Taking only 2-3 minutes to fill 110# sac will be very nice. I will add some underseat ballasts up front if needed but would be nice to avoid

[iamcdn]

Eric, they are not the same. NSS is new this year

[nyryan2001]

Wakeslasher-- Surf vert and NCRS have a HUGE effect on the surf wave. Best results by a mile were at NCRS 5 and Surf Vert 0.

AlianceBJJ- yes there is some exhaust on port side. I surfed my son there this weekend, and it wasnt too bad. If winds are just right.... meaning the winds blow them back into the boat or into the rider it could be a problem. We need somthing along the lines of FAE.... but without being as extreme and crazy as FAE. Just a well designed 6" turn down.

I see you are into BJJ, Ive trained with GJJ and several UFC guys several times... GJJ... by far amazing folks that not only live up to the hype but are well beyond.


Surf Vert seting = NSS. Same Same. NCRS is entirely different setting.
