Brick wall I read on here not to long ago about an additive for old fuel. Someone had posted a link to the site. I have some fuel that's about 2 years old that I think would be okay to burn if I had a way to kick it up a bit. Where my boat is sitting and the amount in her is about 200 gal, this makes it near impossible to remove. Any help would greatly be appreciated.

Tim ,
I'm not a expert on to many things, but i will tell you what i did with mine. There was about 50 gal. in a 88 gal. tank and about a yr. and a half old. Went to the airport and got some avation fuel , high in octane ,no E , and put what i could in. She fired right up, just changed the filters after i burned most of it out . didn't buy any fuel treatments, saved a $ there.
I agree with you that the fuel is good. Might add an octane additive : local auto parts store : and check for trash and water, if you can.
Right or wrong that's i did. She had a more than a ft. of water in her back in march when bought her. Two months ; 12 hrs. a day took her apart and put back together. She's been a great project.
I'm sure you will get better advice than me, but thats how i took care of the fuel problem.

Thanks Mark, never would have thought of jet fuel. Will that require me to install Wings On her?ha ha. Yes we keep her up close to Knoxville, at Fox Road. The BigM has been undergoing major overhaul last couple of years, Partly do to procrastination an a little to do with my real job. We have been able to get a lot done this year with high hopes of getting away from the dock a bunch, Pray this next year. For the last 2 years I have had to settle with starting the good motor and putting a fan on the bridge (wind affect) and closeing my eyes. Some might call that daydreaming.

Avagas will raise the Octane slightly when added to existing fuel. The problem is phase seperation in E fuels and loss of Octane as fuel ages. Loss of Octane can result in pre-detonation. Higher the octane the more resistant it is from detonation. High compression engines require higher octane fuels. More octane than your engine requires is $ out the pipe.

A good product I have personally used on some really old fuel is Seam Foam. It is not cheap about 8 pucks a pint which will treat 12-25 gal. I have found it discounted when buying a case.

Seabrite also makes an E fuel additive. It will keep alcohol in suspension for long periods of time. (over a year)

Note: Jet fuel is kerosene and is NOT to be added gasoline.

Removing fuel from a fuel our fuel tanks can be very dangerous. Years ago fuel tanks had petcocks to drain sediment and water from tanks. Naturally the government has gotten involved and not they are no longer permitted. Some old classic cars had sedimment drains on their tanks. I have a 57 MGA that has on on the orginal tank. A new reproduction tanks does not.

safe boating,

dave

Tim,
This is our third cruiser but our really first project boat. The others were bigger but pretty much turn key. when i saw this little baby half sunk , my wife and i just had to save her. Always wanted a Marinette . They got the best looking lines of any boat.
I had to do all the work at the slip, thank god it's covered. I know what you mean about wanting to get her out when works being done, seeing the others sliding out with the wind in their face.
I know about work and travel , sometimes its hard to make time for yourself. Hope you get her in the water this spring ; Wanda and i will keep an eye out for you. Were just down river ( Blue Springs Marina ).

You should be able to salvage 2 year old gas. I used pri-g in some very old boat fuel to burn 1/2 & 1/2 in my truck. I also used seafoam in fresh gas to run an engine test on engines that had not been run hot in a very long time. That didn't seem to hurt anything.

Here is a interesting link to a company that sells gas testers. They have a lot of bad things to say about E gas.

I here ya Mark, All the work is being done at our slip as well. Adds extra challenge because we are doing it in stages so the boat doesn't look as though it belongs in the junk yard and the area around us is alway's clean. Keeps the neighbors happy. We have all the top side work almost complete, only things left are to replace the window tracks and glass in the aft and forward cabin. mount the bow rail and running gear oh yeah and paint the toe rail. Next project (I've been sayin this for 2 years, but this time I mean it. ha ha) is to rebuild the starboard engine. Then we will run her to the yard in the spring and haul out for painting from the rub rail down and replace the zincs. Then we start on the interior. Good Lord willing she'll be done by fall of next year. Or at least done until I find something else to tinker with.


Applause Thanks for the link Yooper
