Hi everyone: I have previously had water in the fuel problems when we had to use ethanol-laced gasoline. The tanks were professionally cleaned and now I have only Ethanol free fuel. I do not want further problems, therefore how do I know if my fuel tanks are full enough to circumvent water accumulation while my beloved C-Dory is docked? Is there any visual info that I can rely upon?
Thanks

Ted, keep them as full as possible, and use Stabil or an equivalent. You should be able to see your tanks, is that not the case with your boat?
 
From the Boating mag last month I learned that all fuel tanks pick up their fuel from the bottom. (Should have thought about that for a bit first and might have figured that one out), So, if you put a RACOR filter in line and it has a clear bowl, you can see the water in the bottom of the bowl. Drain it off through the petcock, and you should be good to go.

Don't know if Stabil will keep the water out but it does keep the gas from phase separating and keeps the octane rating from dropping. That's what my mechanic tells me anyway.

I would also take a look at your fuel vents. There have been cases of the spray from the boat especially when traveling in rougher seas entering the fuel vents then it finds it's way to the fuel tanks. Attwood makes a different kind of fuel vent that helps to prevent this from happening. Not a hard item to switch we added some clam shells to protect the new vents which are plastic instead of metal. Page six of our album. I believe West Marine has the Attwood vents. See http://www.westmarine.com/webapp/wcs/st ... sNum=50409
 
Are you using an external fuel and water fuel filter ex Racor or equivalent?

Some have a bowl under the filter for visible inspection of debris and water along with drain valve to remove any accucumlated water.

David Pascoe has a written an informative article on water condensation in fuel tanks. It is located at

I have read the article several times and I would look for other souces of water in the fuel
 
Being one who has had boats since I was a young I have had little if any issues with water in the tank. So Far... After reading this article IMHO he is dead on correct.

I have always had at least one and usually two, (SEA WOLF) good fuel filters on my boats. Using one that has a sight glass (Racor Filters) is a must in my boat. Peace of mind... Just one last note. I can't remember the last time I drained water out of my filter and I don't always fill my fuel tanks when putting it away. I always us Stabil every time I fill up. :thup Hope this helps.

There are two schoos of thought on winterization methods and tank storage.

Our recomendation is to store the tanks as near to empty as possible. Draw the fuel out and use in your car if you can.

Yes, there may be a small amount of condensation, but we can more easily deal with condensation than stale fuel and phase seperation. Today's fuels are just incredibly unstable and begin losing octane withing weeks when stored. StaBil helps, and if you are going to store fuel in the tank it must be treated.

In the spring top off with fresh fuel and fresh water separating filters.

Very good advice Matt. One I have never tried but really make sense when you think about it. My boat will stay tucked away all winter with gas that gets older by the day. I have never had trouble in the spring but I do treat the gas twice during the winter months.

I may look into a system to pump out all the gas in the winter and add it to my cars.
 
I do as Matt says.

I completely empty the tanks (I do add Stabil to the tank to treat any small amount of fuel left behind). I also replace the water separating filter at the beginning of each new season. And by the way I have found water, fine dust and debris in the bowl during the boating season! I also cary spare filters and wrenches on board.
