The boat I just bought has a little over a half tank in each tank that has been in there for about a year ,
Can I save this gas buy adding stabilizers and fill up tanks before running

6 months should be ok If it isn't a whole lot, you could add more gas (premium perhaps) and then burn it thru.

that corn gas has all ready started to break down and soak up water don't take the chance on it, pump it. But real gas is different. IMO

How would he know which type of gas it is if he just purchased the boat? Is there a way he or anyone else in the same situation can tell which type of gas it is?

pull some from the tank with a hand pump. you're looking for water or the gas turning dark amber. or with any hope find out where the last owner got his from.

This is hard to establish. If you draw fuel from the tank it could be regular gas with no water present in the sample because your sample was not from the bottom of the tank where water would be if it where regular fuel. If it is ethanol fuel, water becomes part of the fuel and you can't see it. I think it may be a differant color, compared to fresh ethanol fuel, (if such a thing exists) but I am not sure. One thing I am sure of is, you are best to remove the fuel and start fresh.

if the corn gas separates it gets real dark at the bottom of the tank. this is the part that's sucked up the water, then you get a thin layer of water and the junk gas floats on top of it. you can't re-faze the gas the octane is gone. D-fuel you can fix (and what they're doing to that is a whole other story) between what I went through with my merc 454's last yr and both of 350 Chevy's in 2 of my FEDEX Ground trucks I wouldn't deal with it again.( 4 fuel pumps each)

And remember you need to check all your gas lines to make sure they're rated for corn gas, the stuff eats plain ole gas hose from the inside out.(found out the hard way, almost cost me and my wife our life's due to a mech putting it on my gen set and I didn't check it)
