2020 GS22 Bilge Pumps

[rwrose]

Having an issue with the bilge pumps on our GS 22. I read the previous posts and information in the manual on how the bilge pumps work and the various lights, but I still don't think they are working correctly.

Last weekend we took a wave over the bow after dropping a skier at the dock. It was two waves actually and it was quite a bit of water. I checked the bilge and it was over the bottom the bilge pump, so I expected the pumps to automatically kick on and drain it, but they didn't. I pushed the button to force them to run and they still didn't, though I did hear them cycle on for a second. Ultimately I had to put it on the lift and pull the drain plug.

The local dealer took a look this week and they are saying the pumps are working properly, however, I do not believe they went to the extent of adding water to the bilge and having it pump out.

I am wondering if whatever mechanism detects water is not working. I am assuming this is embedded in the actual pump. I did not see a separate float switch.

If this is user error, I think they have over complicated what should be a basic function of turning on the bilge pump manually.

these pumps do not use a float, they cycle every few minutes and if there is no excessive amperage draw detected (pumping water causes an amperage draw) it will not pump it out. then just keep cycling as normal. you said the water was completey over the pump and it still wasnt staying engaged?

Not completely, I would say halfway. Certainly more than I would want to stay in there. Another oddity, randomly this summer I have had the high water alert pop only to find no water in the bilge.

We took in a huge wave filling the bow a few weeks ago in our 2020 SN200, and I was surprised how long it took for the bilge pump to kick in. It seemed like forever, but it was probably just a couple minutes before the front pump finally engaged. The back pump never came on, but maybe it didn't need to. Every time we stopped to pick up a skier the front pump came back on for awhile. We probably should have waited for it to empty out before taking off again, but we are an impatient lot.

We got a high water or rising water alert once this summer too. We freaked out thinking we forgot the T plug. It actually was a little loose. We gave it one full turn and we were back in business. I saw very little water in the bilge though. I'm not sure where those sensors are, but they can sure cause a panic.

Thanks, that’s helpful. Honestly I was focused on rear bilge pump because I could access it. I’ll pay closer attention to the forward and give it more time to sense the water. First summer with the boat. Use to a flipping a switch and the bilge turning on.

The high water alarm is unnerving. I am curious how it works, i.e., what type of sensor.
