G25 extra ballast

[Proedge]

sorry to bump this up, this is the most relevant thread I have found so far. I'm also looking at getting a 2016 G25 and want to figure out if it will make a good surf wave stock. Judging by the posts in this thread, it will take quite a bit more weight to get a good wave out of it. I just sold my 2010 X-55, which I had dialed in for surfing pretty well. The only issue I had with it was having to switch the suck gate all the time and change weight around for goofy/regular riders.
Anyway, now I'm looking at getting a newer boat will be easier to surf. I'm hoping a G25 will do that, but maybe I should consider a G23 instead?

Dean, I see you put around 600 hours on your boat, back in 2018. Do you still have it or did you trade it on something newer? I'm looking at getting a 2016 with 500 hours and was concerned about the high hours. I'm also in BC, was looking at a black boat in Sicamous.

Maybe I am wrong but I don't think that's possible. The pumps are reversible so the same connection pumps water in and draws water out. My extra bags are plumbed with the bottom connected to the overflow of the factory bags and the top of the extra bag connected to the overflow. That way factory fills first and then the extra fills as the factory bag "overflows"

You can use a check valve on the fill line, and a T to make it work. That way, water flows in through the top, but won't come back out of the top.

Yes, I plumbed them in from the hard tanks at the dealer. The only thing I would say is it will work better if you fill the overflow sac from the top and drain from the bottom so it empties properly.

Thanks Dan. I do have NSS and with stock ballast we run ncrs 5 and NSS 5. I have 400lb sacs from old boat and going to play around with them in rear lockers and see how that works and go from there. Did you piggyback from hard tanks on bow and rear sacks? Was it hard to do? Thanks again.

Hello,
Have put 600 hours on since then and can tell you what has worked for us so far
I put 1000 pounds of led from leadwake.com, 400 in the nose,200 in starboard side bench seat and 400 under port bench seat (extra 200 to offset prop rotation), I also put a 900 pound plumbed in sac under the nose seats which I fill till the seats start to rise. In addition I put a pair of 900 pound plumbed in sacs in the rear hatches but they are too much, you really only need 400 at most but usually unnecessary unless there is no one else in the boat.
With that setup most people find 0/0 to be the best setting but people who are 250 or more pounds like a 3/3 or more to keep the push needed. Speed is always 11.2. As you do not have NSS I would keep the setup with the 900 in the rears in addition but only on one side to get the lean you need
Hope this helps?
Dean

Guys,

Hope it is okay to revive an old thread. I have a 14 G25 and considering adding some additional weight. Have a few questions and would appreciate any guidance.
Was it hard to piggyback off of hard tanks in the back and bow?
Is 900 lbs in each for back enough?
Do you have to reset the settings for the pumps to keep pumping?
Where did you all get the bags from, Wakemakers?
With stock we run NCRS at 5 and NSS at 5 and speed of 10.8-11.0 for daughter because she likes it steep but it isn't very long.

Seems like you guys run very fast so may play around with speed. When I try and mess with NCRS wave washes out bad and NSS at 0 the wave is tiny. Any thoughts and advise would be appreciated.
Thanks in advance.

Any time, come on over

So when do I get to ride this beast? Lol looks Sweet.

Here is a photo of the biggest wake so far, full everything and 12.7 mph, 0 nss and 5 ncrs, this is my son and he is 6"1". It is awesome but the truth is you really don't need it and if you surfed like this all the time the fuel burn would be incredible.

[DeanT]

So after 50 hours of playing with the wake I have got close to what seems to work the best for me. Full stock ballast, 650lbs of water under front seats plus 600lbs of led weight (400 equally split in the nose and 200 under passenger seat by stereo to offset prop rotation), rear 1100lbs extra bags about 1/4 full and 0 and 5 for nss and ncrs settings. If you go with any more weight in the back it just becomes way too hard to dial in the wake without wash out and the motor has to run over 4000 RPM which causes an incredible fuel burn. Will continue playing with it and update if I change anything.

Yes I agree that the breaker is over sized. The wire going from the breaker to the pumps is 10 awg so I'm pretty sure the breaker will pop in a short circuit but I'll probably change to a 40 amp just to be safe. I had originally planned to install individual button style breakers for each pump but changed my mind during the install. I had the ballast breaker laying around in the garage so I used it to get the system going without having to wait on parts.

10 awg is only rated for 30 amps. That is the breaker size you need. If you draw 30+ amps your 40/50/60 amp breaker will not trip and your wire WILL burn up. Change that breaker ASAP.

Anyone add piggyback bags on a 2015 G23? What size bags in back lockers? Did you have to do anything in the front?
Thx!
