Mods,  move this if needed but,  I figured if it is correct,  it may get more play here.  I was told by a friend (who also has boat),  that if the gas you use in your boat has ethanol in it,  using Stabil can do more harm than  good.  Anyone out there ever hear this?  

I use Staybil in everything I own that takes gas. I have never had a problem with anything.

Quoted from their page:

Is STA-BIL Fuel Stabilizer safe to use in all gasolines, including gasoline/oil mixtures and ethanol blends (including gasoline with up to 10% ethanol)?  

Absolutely yes!

Stabil has a new Marine Formula to preserve the ethanol blends which attract water.

I always thought that you were not to put ethanol gas in your boat motor. Any truth to this?

 It does sound too good to be true but ifs its around the same price it is worth a shot. These are the 3 big reasons why people who winterize their boat have fuel system issues down the line. So if it works, it will be a better investment than good old Staybil. imo

Live_2_Fish atleast as far as the motor goes Mercury says you can use the gases with up to 10%. They say not to use anything beyond that. I'll find the link and post it later.

Found it quicker than I thought

Cool, I didn't know that.  

Thanks Bassdocktor

As I know Staybil is the good to put in anything and is really good if your storing the equipment for a long time.  I have also heard that it is ok to run your boat on ethanol gas, but I wouldn't suggest to let it sit for a long time.  I heard it's not good to have ethanol gas sit for long period of times, so if you did then I would use Staybil or Seafoam type of gas treatment.

Ethanol gas. Lots places in the country only have E-10 gasoline and it may or may be posted on the pump. I did some web searching and found these products that may be better or equal to the marine Stabil.
