I have 2001 31’open.
My issue is with the shower sump pump .
Where is its location and accessibility?
I’ve had the boat for. 3 years and the pump has cycled every 2-3 minutes .
That has recently stopped.
How do I check the pump to see if it still functions?

Hi,
On my 3300 the pump is located under the stairs going up to the helm. I don't use mine but don't think it cycles, I think it is either on or off. There is a breaker on the breaker panel and a switch for it in the head.
I would take a meter and check the breaker, the switch and the pump to see where the fault is.
There is also a mid-ship bilge in the same area as the sump pump. May want to check that too while you are at it.
Good luck!

I'm not sure if the location is similar, but on my 2010 3200, this was a real pain. The shower sump is under the stairway down from helm to cabin.  I had to take the entire staircase off and pull it back 3-4 feet, and then remove two starboard panels in the deck just forward of the electrical distribution panel.  The sump pump box was under that next to the mid-bilge pump.  The float switch in the shower sump was a rule-a-matic bilge-pump type deal with the little jimmy foot that goes up and down.  BUT BUT BUT - you cannot just replace it with another of the same kind.  I tried that and the float switch would get trapped by the plastic debris filter - it would either NEVER go off (stuck down), or it would get stuck on (lever could not get down all the way to shut off pump).  My hypothesis is  that Rule changed the size of the float switch over the years, and the new ones do not fit right in the old sump box.  I replaced the float switch with one of the self-contained float switches - i think Rule 40A or 40AF.  It fit perfectly and has been working well.  The other option is buying a whole new shower sump, but they aren't cheap.
