I would like to be able to drain the water off the bottom of the gas tank as is done on light aircraft. I would add a plug similar to the plug used used on the fuel water separators. Bad or good idea? Thanks!

I don't feel it meets USCG regs. Most will siphon there tanks. Use some Startron or Stabil Marine and you shouldn't have water.
Wecome to CCfan. Have you submitted pictures and some text for the diaries yet? We always like to see members boats in that section. Tell us more about the boat. Is it a "project" boat?
If you want, add your first name to your profile. I don't know how much time you've spent on CCfan but you'll find that most will use first names here rather than screen names which is common on other sites.

Main problem with that is if you have an older boat like my '85 the tanks are flat on the bottom.
To do something like your talking the tank needs a sump area to collect the water.
I would say that if your getting that much water in your fuel, I would start buying my fuel somewhere else.

Can't you just lower the bow, jack up one side of trailer, then put the siphon hose in the low corner of tank?
Seems like drilling a hole in a good gas tank is a extreme action to take for a small problem. How would you weld a fitting in? kaboom?

Your advice was spot on. Thanks!! I just posted in Diaries, but it did not take. Will try again. The boat is a stock 1984 CCSN and it will stay that way.

I think a fuel sump drain on the water seperator is a great idea. I have used them a lot on many small aircraft and commercial jets. The problem I see is that on an aircraft if the drain leaks, it will leak into the open air and won't cause a fume or fire hazard, plus if it is avgas, you most likely will notice the discoloration from the Avgas on the paint. In a boat, a small leak could cause a vapor problem and/or explosion. The only ones I have ever seen leak are the ones that aren't used as often as they should be, so maybe it wouldn't be a problem. If you are buying good gas you shouldn't have a problem. I just replaced my fuel filter and noticed that the bottom of the seperator was a rusty color, but I just purchased this boat, so I have no idea if or when it was last checked or changed. I plan on draining it annually and hope that will be ok.

I have a 96 SN with the fuel cell thing which also acts as a water separator.
I prefer to drain my gas tank and had struggled with how to do it for a few seasons. I tried siphoning from the fill hole...didn't seem right or couldn't really drain it. I tried a hand pump but couldn't seem to get a good drain going. I tried using the fuel pump but it only does a little squirt each key power cycle on.
I think I got it this year.
I disconnect the input from the fuel pump at the fuel cell end. I attach some extension hose to that to go into a gas can.
I disconnected the wires going to the bottom of the pump and rigged up a cable from the 12V accessory plug to the pump after figuring out which was positive. Pressed the breakers and voila constant stream of gas pumping into the gas can.
Now my tank is mostly empty and away it goes for the winter.

The best way to keep water out of your tank is to keep it full. Most manufactures suggest storing you boat with a full tank and a stabilizer. My tank is mostly empty and I will fill it with half Avgas and 1/2 pump from the station for storage.
