Can anyone tell me what this pump is for. I cannot figure out what it runs, pumps or is attached to? This is on a 2000 - 382.

That pump is to drain the bildge area under the step in the cabin.
The only way to turn it on is with the float switch.

There is a float swith with a bilge pump in the box under the step, I do not understand the puropse of this pump?

I found out by winterizing the AC system and dumping alot of pink antifreeze under the cabin step. I'm guessing that type of pump can pull water a great distance so they use that type. It sounds funny when it comes on but it pulls most of the water out of that area. Remember with a stepped hull water gets trapped up there.

The pic you posted is of the pump for the bilge.

The pump that is in a box under the step is to pump out the drain water from the sink and any drain water from the floor in the head.

thats what I thought, looks a lot like my bilge pump

It is a remote pump that helps pull water from the cabin step area. The pump up there isn't strong enough. The shower drains into the step. The bige is pumped with a pair of conventional Rule pumps under the engines.

Looks like the Jabsco bilge pump on my boat. I just replaced it last year. They ain't cheap.

you will find two float switches under the step that are not in the shower sump.
The switch looks like a blue box, you can turn the pivot pin and activate the pump.
The lower one is for the pump and the higher one is for the high water alarm, the alarm takes a few seconds to sound if you want to test it.
I hope this helps.

Thank you all for the response, it was a great help and now I know what it does since it has never been activated until I winterized it.
