"ACCY" Switch on Wellcraft Sportsman 220?

[mhamel40]

Hi all:

Newish owner of a Sportsman 220 (2005). New to the forum, thanks in advance for any thoughts/suggestions. I am the third owner of my Sportsman. Prior owner had it in a slip, professionally maintained by a reputable marina. I went out this weekend and was having difficulty getting the boat up on plane. I am investigating the issue, and obviously am looking at the engine (Yamaha 200, same year), but I am looking at a few other potential issues.

There is a switch on the control panel labeled "ACCY." When I run it, I can hear another pump and can see water pouring through the storage compartment and into the bilge/out the drain. The bilge pump works fine as far as I can tell. I also replaced the washdown/livewell pump. I know these boats are known for fishbox drainage issues--that doesn't seem to be the culprit here. And I checked the bilge multiple times while out there--it wasn't full.

Could my bilge be hooked up to this "ACCY" (maybe a macerator) pump? Where is this water coming from? Any thoughts? I am wondering if I was weighed down and that could explain some of the planing difficulties. Quite a bit of water came out the transom drain.

Thanks in advance!
