I have read a post with this problem before and yes one guy was getting water in through the vent, clamshell fixed it. other guy was getting water collecting on top of his tank therefore leaking through the level sender gasket. First thing I would check is the fuel from the gas station you use, get some and pour into glass and let settle. It has been known to get water in gas from a gas station.
Good luck

If you just bought it, then the water was probably from the previous owner, but who knows?
Keep and eye on it and avoid Ethanol if possible...

I think it has to be the vent. That thing is facing the sea and also sucking in when running. I am going to put a clam shell over it and I think that will take care of it. I use my boat 1-2 times a week so my gas is constantly getting cycled and does not sit. I have only owned the boat for 2 months.

I think you're right. It HAS to be the vent. Unless water is entering from the top of the tank at the fuel sending unit, there's really no other place that much water could get into the tank. Out, yes, but not in. Mine is an 04 and has the internal vent. I'm guessing that 03 was the last year of an external vent on the 2100s and there has to be a reason for that.

I had the same problem on a Sea Boss that I had with that vent. Ended up doing what someone else suggested, claim shell.
On my Sea Pro I broke of the plastic cover over the vent and every year I had to clean the injectors. Ended up having a flush mount vent put on the boat. So far so good.

I have been dealing with a similar problem on my 2005 206 CC but 10 gallons of water in the tank is pretty outrageous. If you are pouring pure water out of your separator I would immediately check the filter under the cowling and then move on to the fuel rail and VST filter if you have one. I would be very concerned that the fuel rail has water sitting in the bottom of it (assuming it is set up like my F150) and that the bottom injector and cylinder is sucking water out of the fuel rail. If nothing else, pull your plugs and see if that bottom plug looks different than the others.
I have no way near as much water in my fuel but it showed up after running for a couple hours after my first fill up after installing a brand new fuel cell under the deck. I've racked my brain figuring out how about 1/2 gallon got in 75 gallons of non-ethanol. There is no way 10 gallons could get in through a fuel vent unless you were running through some hellacious seas. Do you have any enemies that might like pouring water in your tank? It's something that I took care of by installing a locking gas cap. I also changed to a clam shell angled to the stern at a 45 degrees AND PUT AN UPWARD LOOP IN THE FUEL VENT HOSE IMMEDIATELY AFTER THE VENT CONNECTION. This to assure that any water that gets in to the vent drains back out. Then I swapped to a 2 micron water/fuel separator filter. Some may disagree that this is a good idea but I am good with it. I had the injectors pulled and bench tested. 2 were pumping like crap and had to be rebuilt.
My water issues are mostly gone although I still get a little in the seperator after a run on flat seas, so it is not new water thru the vent, it is residual from the leftover water that is sloshing around on the bottom of the fuel cell. Time and frequent checks of the seperator will cure that.
On last thing.... Do you run in saltwater? Taste the water you get out of the fuel,. Is it salt or fresh? That should tell you something.. ( no don't swallow it).
Hope this gives you some ideas.
