Engine running rough.... Here we go again !

Is the big mistake. I read all over the INTERNET that 'Sea Foam' and ethanol do not mix. Other than that, it should be a go!

If you have a fibreglass gas tank, you should have it checked out. Ethanol and fibreglass do not mix.

There is an in-line fuel filter just before the carburetor. Unrelated to the fuel/water seperator. Check for debris in the filter.

"Treated gas will Stabill, back in late Fall as usual (the red stuff)."

Your problem is most likely fuel related.

The red stabil should never be used with ethanol gas in a boat. This type of stabil is alcohol based and is only sucking more water out of the air through you tank vents. Remember ethanol IS alcohol so by adding more alcohol you are making the situation worse. Seafoam is also an alcohol based product.

Edited to make the following correction: The newly formulated RED Stabil no longer contains alcohol and should be safe to use with ethanol fuel.

They continue to sell the red Sta-Bil and it is causing havoc with fuel syswtems everywhere. It sounds as if you've got some water in the tank which of course settles at the bottom. Before again trying to syphon it all out again I would dump a full 8 oz bottle of Startron into the tank and letting it run to try and clear it up. Not alot of options short of draining it all out,and then what to do with the tainted fuel. PM me BD if you need a hand.

This is true. The following is copied from their website.

Stabil Fuel Stabilizer(the red stuff)

STA-BIL Fuel Stabilizer is America’s top selling fuel stabilizer. Stored fuel can go bad in as little as 30-60 days causing gum, varnish and corrosion to build up in the fuel lines and engine. STA-BIL is recommended to be used AT EVERY FILL UP in all vehicles and equipment to protect against corrosion caused by today’s Ethanol-blended fuels.

Marine Formula STA-BIL Ethanol Treatment & Performance Improver (Blue stuff)

Marine Formula STA-BIL Ethanol Treatment & Performance Improver contains DOUBLE the corrosion preventers and more than FOUR TIMES the fuel system cleaner than in Regular STA-BIL to prevent against corrosion and deposit build up in Marine Engines. Use AT EVERY FILL UP to protect your boat or other marine equipment from the damaging effects of Ethanol in the marine environment.

Hope this helps about the misconceptions of the Red stuff.
