 I'm am seriously considering running this in my boat. My fast xfi computer has a table for this and gm makes a sensor that you can plug into the  fast ecu and it will automaticly adjust to the different fuel. This is why I'm considering it.
 1.The price of a gal at the pump in pomona is around $2.-$3 for E85 verses a gallon of race 110 octane  $8-$9 a gallon. Even burning 30% more I would still save a ton of $ on fuel.
 2. HP increase. I will see a 8-30% hp increase. I would see a hp gain of around 80hp to 150 hp.
 3. The fuel burns cold so it works as a inter cooler in a way. keeping my etg down the motor runs colder and less likely to detonate. A cool motor is a happy motor.
 3. This fuel burns a lot cleaner, keeping engine parts from carbon build up and the motor clean will help with wear and tear.
 4.Using this fuel you can run a lot more boost,compression or nitrous with out detonation. I have a 300 shot now. I could easily step it up a 100 hp or 2 with no problems.

  Using this fuel calls for some up grades that Ive already done. Big fuel lines and ss hose's with an ends, bigger injectors, and a fuel pump that will handle the 30% increase. I don't see why I shouldn't run it. The only cons that I see is that E85 like to absorb water and It burns clear, could be dangerous. Other than that I don't see why not.

 What do you guys think? Have any of you thought about it?

How often do you use the boat? I dont know about this app but my race bike runs on methanal and you have to drain the system everytime, pull the carb bowl and douch everything down w/ WD-40 when done riding it. You should go thru fuel fast enough to not have to worry about it drawing water.

 Methanal it a lot more corrosive than ethanal. Also because it's 15% pump gas you do not have to purge your system or anything like that. Remember there's millions of production cars running this fuel with no issues. I don't have carbs on my app anyway just injectors and the e85 is a clean fuel so I don't have to worry about it. I ran alky aka meth on a dirt bike as well and had to purge it at the end of every day I rode it so I understand what your saying.

I am considering it as well on a new engine build. Gathering info right now, but sounds like a winner!

Well, they run snow mobiles and quads accross water all the time. Just gotta go fast enough. This thing has a greater power to weight ratio than an Indy car. It's like 14-15:1 no brakes but'll stop on a quarter.

 I wish there was somewhere closer to me where I could get E85. The closest place is a 100mi round trip, in the wrong direction.  If they open a station closer within the next year, I will be running it in my new motor.
Welcome to the club of broken boats :o  Pay here$ bend over and move along.

Politic for it, Jeff. I started thinking about this a few months ago, and there are no less than 6 stations in nearby Coolidge (About 1/5 the size of Casa Grande, WTF?), and kept buggin the local stations for it. They're all carrying it now, and it's selling better than gasoline, they tell me.

Only a matter of time before it's popular near the water. Someones gonna try and regulate emissions on these things sooner or later... :screwy:

 Ray if your serious throw some hi compression pistons in there. At least 13-1 to 16-1. While your tanks are out weld in -8 or even better -10 bungs for your fuel lines and run an stuff. Also run some fuel tank breathers and seal up your caps. You may need to weld bungs for breather lines like I did. I ran -8 lines for the breathers. E85 has a octane rating of 105 (ron) but there are tons of guys running 30 lbs of boost on there motors with out any issues. Even though 105 rating doesn't seem very high, Because it burns so cold and its a different type of fuel in actuality its acts like more in the range of 116-120 octane when compared to gas. I wish I knew more about this when I built my motor. Now I need bigger injectors and a couple new fuel lines. No biggie I have tons of extra an stuff lying around but the injectors will run close to a boat. "break out another thousand" :banghead:

Were getting ready to put a blown injected motor in a jet and its going to run on E85. From what ive learned is that the fuel cant stay in the line for more than a few days and you have to use stainless tanks. I guess the E85 will corode  aluminum.  Matt
My girlfriend and my boat are the same,they both suck and spit.

Yeah, that's why I'm kinda leaving my tanks alone for now. Got these stainless ones I got off Brad that will need extensive modifications to even fit in the gunnels, so PERFECT for cutting up with a million bungs...........That just sounds nasty.......

What about plastic tanks?

What about plastic tanks?

 Ok Ive done a lot of research on this and so far from the factual information Ive dug up, plastic and fiberglass tanks are the worst to use and you cannot not use them. Stainless is the best. Aluminum  is the third best after the 2 types of stainless used. From what Ive read witch is very interesting. the government is claiming that aluminum is not compatible along with a list of things witch have been proved otherwise. ( I feel a bit of conspiracy going on with e85 and the government)  From reading post on multiple threads dating back to 2001 on this subject, many if not thousands Have little or no problems with aluminum and E85 over several years of use in daily driver cars, boats, and motor cycles. In my conclusion I learned that If I keep water out of my fuel tanks by plugging my vent hoses prior to running, keeping the fuel tanks either full or empty, Full during a short term storage, and empty for long term storage witch I already do anyway I should be good for a very long time. The other option is to hard anodize the fuel tanks fuel rails and any other aluminum exposed to E85.

this was my reasoning for not doing e85, but i got stations all around me for this stuff! hmmmmmmmmm....maybe i'll order 12-1 pistons instead
