Taking On Water/tanks Leaking?

I have read, and even posted about this before.
When we are Wake surfing, I noticed my bilge pump comes on quite a bit, I would say at least every 10 minutes or less.

Today I noticed I was also losing some of my ballast, while Wake surf in.
It took almost 90 seconds to refill my rear tanks on a twin pump X20
My center tank also needed to be refilled approximately 90 seconds.

I realize there is some water in the bilge on every boat I ever owned, particularly when you are heavy with ballast.
But the bilge pump running often, and the ballast tanks need to be refilled , Makes me a bit concerned.

The X 20 rides with an exceptional Bow height, and the Stern is always very low in the water, I don't know if that has anything to do with it.

Is it possible my tanks are leaking, or the manifold that connects them together?

I would check the hoses before suspecting three cracked tanks. Launch the boat when everything inside is dry, fill ballast and just float. Look around and see if any water starts to build up or if any water is leaking out. Not sure if it's possible to remove the ballast sensors and fill with a hose, that way you can check in your driveway and not worry about water coming in from any other sources.
I know my X25 has the same style transom and it's not hard to get water up on the seats and down into the hull.

I have had both quick release connectors pop loose at the bag, and the flange of the intake crack at the bag both from larger than stock rear bags and the pressure they can create.

Others in 2014 reported cut or cracked tanks.

Ymmv but worth checking all systems.

Did you get the screen squared away?

I notice we get fair amount of water in the bilge when we are wake surfing and the bilge bump comes on from time to time. I know the transom is low and when we stop abruptly water swamps the rear of the boat and drains into the bilge. I try not to stop abruptly to prevent this, but when the lake is busy I don’t like leave a large gap between the boat / rider so it’s not always possible.

I would test your ballast tanks one at a time to be sure there are no leaks. You may be losing water through the ballast pumps...have you changed / checked the impellers?

Do you know if the previous owner properly winterized the ballast tanks? It would be a real drag if they are cracked and leaking.

So. The bad / worn impellers can drain out backwards?
Maybe that's it?

That is my understanding...the impellers act as a seal when not in use.

Did you try replacing the batteries to see if that fixes your screen issues? The odds of having two bad screens has got to be really low. Iíll bet it is something else.

I notice I get water in mine when I stop and waves come over the back. That could explain water in the blige but not the tanks leaking

Larry - As said, I would be shocked if all 3 tanks are split, especially the KGB. I would first replace the impellers, as they can siphon. Second, I would check all your connections, when I found my cracked tank, the rear connections on the tanks from the factory were not very tight.

When my tank was split, I got a lot of water pretty darn fast, both bilges would run as I was running, turning to pick up a rider, and emptied my bag in one set.

On my X25, I do get a fair amount of water from the back wash into the bilge.

I had the same symptoms as you in my X25. But only one tank would lose water, not all of them. Turned out I had cracked hard tank. Sent it to MC Corp for repair. Got it back. Month later started again, this time other side. Hard tank cracked.

I could see water flowing into the bilge. Wasn't a river, but you could see it. And the bilge ran hard to keep up. That sucked. Truly hope it's not the case for you.
