G23 ballast filling after drained and power off

[sja]

I know this sounds improbable, but the ballast tanks on my G23 fill up with water after dumping the ballast tanks and turning the power off. After sitting for several hours the port and starboard tanks will read 50 to 100% full. This is not just a reading error as when I push the fill button, they spit water through the overflow ports. Also they do empty all the way when manually drained.
Anyone seen this?

Not with my G23. But if you have a broken impeller in your Jabsco pumps, or they installed the really soft impellers (yellow I believe) they will let water enter when the pump and ballast tank are near or below the water line, as they are in the G.

Thanks for the reply.
Correct me if I am wrong but I believe that the readings on the screen aren't actual levels but reflect how long the pumps have been running. The screen is actually reading that they are full. I thought the pump had to run for that to happen.

I do not think they are timers by measure revolutions. But if they are still timers, then yes the pumps must be running. If that is the case, make sure your return to dock settings in the Users menu have not been altered to include some ballast.

Yes I am having the same issue on my new 2013 G25. My dealer says Nautique is aware of the issue and is working on a solution. I reported the problem over a month ago but it hasn't been fixed yet. I need to keep the valves closed when not in use to prevent them from filling. Very irritating.

I have had the same problem as well on my 2014 G 23. It is my starboard side bag that fills by itself and only on occasion. I'm thinking that the only way this water could make it through the jabsco and siphon into the bag is if a small piece a green plant gets wrapped around the impeller letting water slowly leak by. Yes, this is frustrating !! I had a friend who walked by my boat in the marina call me tonight saying my G is leaning to the right again. I'm going to pull the cap off the pump before I drain it to see if there's anything obvious.

the readings on the screen for the ballast, are control by a ballast pressurize sensor located for each ballast, not timed or gauge level control... I know this because I had problem with my port ballast reading 3/5 full every time I would cutoff engine, and then restart. you can imagine how this would affect the different settings, replaced sensor , back to new... warranty problem , so I worked though white Lake!!!

Funny you post up about this... Just this weekend I was questioning myself if I forgot to drain my tanks, could have sworn I did drain them...I had left the boat in the water overnight. I will watch them more closely.

I have had the same issue with my tanks. Something else to think about… make sure your tanks are completely empty before parking your boat inside (or close the valves in the bilge). One day I came in to find my warehouse flooded because the tanks didn't drain all the way and they leaked out through the pumps.

I own a 2013 g23 that was delivered in May 2013.

Follow up:

100% yes. They do fill on their own... Over the course of a day 12+hrs.

Left it in the water all weekend.

Sat AM. Port added approx 1/8 and starboard maybe 1/16th. Left it with all tanks empty. fri eve.

Sun AM. Port added approx 1/8, and starboard added 1/3 overnight.

Belly never filled.

Maybe this is a design feature Nautique put in the boats so they would be sac'd out and ready to go first thing in the AM. Joking. Needs fixed ASAP, it's 2014, ballast siphon, airlock and all those issues should be worked out by now. These are 2005 problems.

I'd take 1/8 to 1/16 over 12 hours at this point. I'm experiencing 5/8 to 7/8 over 2 hours starboard and 1/4 to 1/2 port side over the same period.

Agreed this does not speak to the quality that I expected from the brand or the level of boat I thought I was purchasing.

[nyryan2001]

^^^ thats a signif problem. Imagine if you had a small tear in one of your sacs and it decided to autofill.

if yours is pulling in that much, you need to use your seacocks all the time you are not ballasted doing watersports.

Agreed, but the G maybe unique. I am trying to think of another model that has its pumps and sacs below the water line before the G? MC always had their Jabscos above the water line but their tanks were also above the water line. Even then, if the softer impellers are used tanks will auto fill. I believe that all the other newer models with ballast below the waterline are gravity filled systems? But I maybe mistaken.

I suspect they will need to switch to the stiffer impellers, raise the pump location, or run the tubing from the ballast pump to the sacs to above the water line. Or, and solenoid to auto open/close the thru hull.
