I have a 2013 2700ES. I am dealing with an odor issue in the head, and one of the things I did after pumping out was to flush about 20 gallons of water down the floor drain to eliminate anything that might be trapped in the drain line. All the water drained, so I know I don't have a clog in the line. I have looked, but I can't see where the water going through that line exits the boat. Does anyone know where the water drains?

It should be going into a sump box and then pumped overboard thru a hull port. Find the box & follow the hose.
FWIW, water standing in that sump box can grow all sorts of ugly stuff! That could be your smell.

Sgilbert, I should have also added, this is the second year I have owned the boat, I bought it from the guy that was in the slip next to mine, and he never activated the head when he owned it. When I bought the boat at the beginning of last year, I had the head activated before the boat was put into the water, and we used it all last year without any odor. The sink drain runs right out of the boat from a hull port right under the sink. I don't understand what the purpose of a sump box would be, as there wouldn't be a reason to hold the water, before discharging overboard, also there doesn't appear to be another pump on board that would empty a sump box. As I said, I ran about 20 gallons of water through it, maybe more, and no pump kicked on. The only access I have where I see any tanks is when I open the motor box, and I can see the fuel tank, and the fresh water tank, I don't see anything that could be a sump box.

I'm not familiar with a 2700ES, but have a look see under a step if you have a cabin. A sump box would have a pump inside it.
The reason for a sump box is the drainage of water that is at or below the water line. Gravity cannot drain a shower drain; hence the sump box/pump.

Note that a sump box for a shower is only about 12"x12" and maybe 6" tall. In a 27 it's probably on the centerline of the boat a little bit aft of wherever the shower is in order to have gravity on your side to get to the sump box.
If nothing is kicking on when you run gray water, the sump pump and/or float have died, and the box is overflowing into your bilge, and your bilge pump is taking care of it.
You really need to figure out where water is going before you dump 20 gallons of anything into an unknown abyss. If your sump is in a stringer compartment and the limber hole drains have plugs in them, you're filling up a section of the hull with water with no escape. I know this sounds insane, but it happened on my Regal 2665 when a dealer failed to winterize the a/c properly, and first trip out a compartment filled with water due to a crack in the A/C sea strainer. I had to start the engine and pull a limber hole drain and let the bilge pump run for quite awhile.
Regarding the smell, where is it coming from? Is it coming out of the head or is it just in the bathroom? If someone didn't use a head for a long time and it dried out, you need multiple rounds of filling and pumping to get the black tank clean. Filling it about halfway and using something to break things down like RV Digest-it will make a big dent. Bonus points if you drive around and let it slosh a bit before pumping out.
Grey odors can be just as bad, this may sound lazy but a sump box gets to a point that I just replace it because getting them clean after years of use is extremely difficult.

Zane, the boat is a bow rider with no shower. I thought there was a possibility that it was draining into the bilge when I couldn't see where the water exited, but the bilge is dry. The head wasn't dried out, it was half full when I pumped it out. When they pumped me out, they also filled the black tank, and pumped it out again. I haven't been able to identify exactly where the smell is coming from, it's just in the head compartment. I thought I would do a process of elimination; pump out the head, and rinse the floor drain. I have purchased holding tank deodorizer, which I will add when I go to the boat this weekend, and I treat the fresh water with Starbrite water treatment.

Well, there is an former engineer that worked at Regal that is at my local Regal dealership who I spoke to on Sunday, that pointed me in the right direction, and I have my issue resolved. He explained that there is a plug in the stringer directly in front of the motor, that is required by the coast guard, so that in the event of a fuel leak would keep the fuel from entering the bilge with the bilge pump and getting pumped out. He told me to remove the plug. After I removed the plug, about 30 gallons or more of smelly water drained out into the bilge, which got pumped out of the boat. I went to the boat yesterday, and I no longer have the odor. There are 2, drain holes, located on either side of the hole that I removed the plug from, but they are about 2"-3" higher, due to the V configuration of the hull, which when after a certain amount of water accumulates, will drain into the bilge, but it retains quite a bit of water until that happens, and all the water will never drain. I will be leaving the plug out so I don't have to go through this again.

That's called a limber hole, and I highly recommend removing the plug.
You should have a bilge pump forward of that hole. have you checked it?

I have removed the plug, and have no intention of putting it back in. There is no bilge pump forward of that stringer, the boat is a bow rider. Also, as I mentioned in my last post, a former engineer from Regal works at my local Regal dealer, and we discussed how the drain lines ran, and the hows and whys of how the boat was constructed, and he didn't say anything about a forward bilge pump.
