fuel stabilizer

[HARLEYBOY]

Hey guys new boat & motor, Yam.75 Hp four, guy come by today does alot of crappie fishing, and asked if I was using a fuel stabilizer ? told him no because my dealer told me if I was using my boat alot would not need it ?
I go out maybe 1 or 2 times a week fishing , He told me just cost him $100 to get the water out of his and it was because of the gas he was using, said I needed to start using fuel stabilizer in my fuel,
Do you guys use it in yours ? if so what kind is the best for my YAM. FOUR ?
I know if I store it for awhile I need to use it but right now hope to be able to fish alot , also do you guys use any type of fuel/water separator filter?
if so what kind is the best and easy to change the filters?
THANKS

I have a 115 Yamaha 4 stroke...been running it for almost 4 years now without any problems. I do just like my Yamaha dealer told me...I mix Ring Free everytime I put in gas and I also use Stabil Marine stabilizer. Yes I do have a external water separator filter. The filter is easy to change ( change it every year). I have been running the 10 percent ethanol gasoline for a couple of years now and have not had any problems. I fish several times a week and I still do this...it was recommended by the dealer that I bought my boat and motor from.

Use Stabil Marine e10 AND a water seperator (Attwood from Wallyworld)

If you are using your boat twice a week you don't need a stabalizer. I would install a water seperator tho. One rated at least 10 microns. Some have a drain in the bottom so you can drain the water out if needed.

My dealer did not say anything about ring free, I have a 20 gal. tank how much do I use?

I use Stabil Marine all the time and increase it in the winter when I don't plan on fishing for a couple months. I also hear when they add the ethanol to your gas it can hurt your motor unless you use the Marine Stabil. I never used it before this year, but always used the old kind before they had the marine kind.

I try to put the regular kind of Stabil in all my gas engines to help if I don't use them for a while ( like tillers, weed eaters, etc.)

Good question and you got some good answers! Here is something else to consider.

The shelf life for gasoline without ethanol is at least a year and probably two. The shelf life with ethanol is three or four months. Ethanol has an affinity to attract and absorb water. To my knowledge, there isn't a product that will prevent water absorption of ethanol. It is the water absorbing properties of E10 (10% ethanol) that makes ethanol gasoline difficult to manage. To illustrate the difference, regular (non-ethanol) gasoline can dissolve 150 ppm (part per million) water at 70° Fahrenheit. A 10% ethanol blend, at 70°, can dissolve up to 7,000 ppm. That is 50 times! Boats love water but boat engine do not. Boats tend to not have very tight fuel systems. Fuel vents are seldom closed and are a source for moisture.

Newer engines (less than 10 years old) are designed to tolerate at least 10% ethanol. Older engines are not. You could experience failed seals, plastic components and O rings from ethanol. Some things that will help is a water separator, keeping your fuel vents closed when possible, avoid fuel additives that are alcohol based (Evinrude 2+4 fuel conditioner is 95% alcohol!)(Sta-bil products do not contain any alcohol), use mid-grade gasoline instead of regular (water absorption can cause the loss of 3-4 points of octane), buy your fuel from a busy name-brand gas station, do you best to keep your fuel fresh, and become aware of the symptoms of bad gas. These symptoms include stalling, hesitation, excessive exhaust smoke and clogged filters and carburetors.

The obvious solution is to not buy ethanol fuel but that is easier said than done. First, it is hard to find fuel today without ethanol and second the States of Indiana, Kansas, Kentucky, Maryland, Michigan, Minnesota, Missouri, Nevada, New Hampshire, New Jersey, North Carolina and Ohio do not require ethanol labeling on gas station pumps. We don’t know what we are getting.

Sorry for the long post but an interesting topic!
