G25 extra ballast

[DeanT]

I am now going to plumb 2 1100 lb bags in the back storage lockers, a 650 lb bag that wraps around under the front seats and then fill a 1000 lb tube bag on the floor with a tsunami pump, and with that bag i can place it forward or back a bit depending on how the wave looks. Hope its a great wake that does not wash out the NSS. I will post some pictures later in the spring when I can get it on the water.

I will be selling some fly high 1100's if your interested? I could drop them off at wizard for when you pick up the boat!

Do you have any pics as to where you put the through hulls and where on the dash you put the switches? I am very interested in this sort of automated setup. Did you do a new overflow, or do you just watch the bag carefully, or just tie it into the stock overflow?

Sorry - I have been out of town a lot lately and just now got to take some pics. The through hull pick ups were new holes. For the overflow I teed into the existing overflows using check valves.

Nice install!

One thing of note, that would concern me a little, is your breaker sizing. A 60 amp breaker is way oversized for the downstream wiring. You don't want the breaker rating to be any higher than what the downstream wiring can handle. It looks like you have 12 or 14awg wires going out of the breaker. I would downsize that breaker to a 30amp. 40 at the absolute max.

If one one of those pumps ever shorts out, you will end up letting the smoke out of that wiring, and that smoke is very hard to get back in...... especially if the rest of the boat goes with it!

Great job on that setup though. Looks factory. Well done.

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.

Gotcha! Ya, much less risk with 10awg!

So I finally was able to get the boat out and break it in and wanted to post what I learned. In the end I put 2 1100# sacs in the rear lockers plumed into the existing pumps and a 750 under the nose also plumbed into the belly tank. with this setup I can not fill up the rear 1100's all the way without washing out the wake, I can really only run them about half full, but even with them half full the wake was awesome! I am going to try putting 5-600 pounds of lead in the nose and try some more testing, I have not got it fully dialed in but will and will have fun trying.

Nice water. Where are you located?

1100 on each side in the back is probably too much. What's happening is that water is flowing overtop of the NSS plates with that much weight back there, and that's why the wave is washing out. There is such a thing as too much weight when using NSS. More weight in the nose will probably let you run a little more weight in the back than you currently are with the 1100 sacs half full. Keep playing with it and I'm sure you'll find the best setup. The wave you posted above looks very nice!

It is at Christina lake, BC

I too am experimenting with extra ballast in my G25. The boat was new to use last summer so we spent most of our time enjoying it stock and not tinkering with it. I did have bags from my last boat and on two occasions put those in. If I am remembering correctly the stock surf setting is rear bags full and the belly bag 1/2 full.

On the first try I added a full 900lb bag to each rear locker and filled the stock belly bag to 100% full. The wave was washed out and I had to dump water from the rear bags.

On the second try late in the season, I again added a full 900lb bag to each locker, fully belly bag and a full 500lb bag in the bow. The wave formed and was very good. I think it could be even better with lead bags. The 500lb bow bag rolled back against the bow seatback near the windshield. I am hoping with lead bags I can stash those at the very front of the boat and get a better effect because of leverage.

I purchased 700lbs of lead bags from www.leadwake.com and plan to put 500lbs in the very tip and use the other 200lb to counter prop rotation. Another thing I am going to try is slightly listing the boat. If I am 100% full on the surf side, then maybe go 3/4 on the nonsurf (NSS) side. That should help raise the side of the boat that deploys NSS and address the issue Jeff raises about submerging the top of the NSS plate. Obviously the downside to this is you cant do transfers.

Lets keep this thread going as we experiment. There aren't many threads on slamming the 25s. We will be back at the lake on Mothers Day and I plan to add the lead and see how it goes.

DeanT. What 750lb bag did you add to the nose? Is it under the seats?

[Shockthis]

You cruised by my house (blue house by the boat launch)and me and my buddy where on the dock wondering if it was a 23 or 25 . I guess he was right it was a 25. If you need help dealing it in we are pretty good at it. We both have nautiques.

[DeanT]

Hi Bevostein,

Yes, it is the fly high sack under the front seats and with it full there is still quite a bit of room for lead, I am going to put as much as I can in the nose and then some more under port side where sub is located. I will update you again but it will be the end of June before I get into it again.

Yes the First Gen G hulls like abit of list. on my G23 I use 650's in each locker full then fill stock ballast full on the surf side and opposite side only half full. Perfect wave and I've never had any issue with washing out. Belly also full and 300# lead in the nose.

[DeanT]

So, I have finally had a chance to surf my new boat and wanted to post some findings.
I ended up putting 600lbs of lead weight (leak wake) up front in addition to the fat sacs to try to sink the boat evenly, 200 just in front of the sub and 400 around the nose fat sac. I was able to put about 850 in each rear locker without washing out the NSS and at 12.5 MPH I had a fantastic wake and must have been 30 feet behind the boat while surfing. I will continue to
play with it and update but super impressed with the wake so far! I was less impressed that I had to get towed in because the boat quit and would not start again.....
