Even Evinrude tells that it's harmful. Outboard repair shops here in the south are full of small outboards needing repairs due to ethanol.Star Tron Convert

From Suzuki Outboard Forum
I had been having increasingly poor idle and poor low RPM performance. Starting as like a magic trick with setting a high idle and quickly shifting into gear, hopeing it would not stall. My DF 70 would cut off and the worst times....approaching the dock...slow maneuvering etc. The problem started slowly last year and has gotten worse until I felt that the shop was the next stop.
I fuss over my engine and keep it up well. Cleaning and checking here and there. I new set of plugs did not help. I blew out the fuel system and checked for water. Cleaned all the filters. All clear. I regularly run Suzuki brand fuel injector cleaner mixed with the fuel.
I did a lot reading and researching and decided to run some Star Tron Enzyme Fuel Treatment. BINGO! With the first 6 gallons things started looking up. Better idle and starting. Smoother low PRM running.
24 gallons later. Have my old DF 70 back with all the great performance I was used to.
Damned E 10 fuel to hell. Put the corn on the plant not in the fuel tank.
I am a Star Tron fan and plan to be using it for a long time.

MARINEStar Tron? Enzyme Fuel Treatment is a revolutionary new fuel additive using enzyme technology to enhance the performance of boats, automobiles, trucks, RVs, tractors, farm equipment, generators, lawn mowers, lawn equipment, oil burning furnaces and all other small engines.
Dramatically Increases Fuel Economy
Star Tron? cleans the entire fuel delivery system, removing performance robbing gum and varnish deposits while modifying how gas and diesel burn, this results in more complete and uniform combustion and therefore better fuel economy.
Eliminates Black Soot and Exhaust Stains
With the removal of harmful engine deposits and an increase in combustion efficiency, exhaust emissions are greatly reduced. This results in cleaner air and cleaner boat transoms as black exhaust smoke is noticeably reduced.
Removes Carbon Build-Up
Carbon deposit formation is a byproduct of unburned fuel in the combustion process. Star Tron's enzymes will break down and disperse these deposits restoring engine performance as it also modifes the fuel to prevent future carbon deposits.
Disperses Bacteria
Commonly referred to as "diesel algae," these microbial spores will colonize in the water phase. Startron slowly disperses bacteria: the fungi, mold, and yeast, collectively known in the fuel industry as "diesel algae", allowing the fuel filtration system to function efficiently.
Stabilizes Gas & Diesel Fuels
Gas and diesel fuels break down rapidly which results in lost power and poor performance. Star Tron stabilizes the fuel chemistry for up to two years in gas and two years in diesel.
Eliminates & Prevents Ethanol Fuel Problems
Ethanol / E10 fuels increase the amounts of water and sludge in your fuel tank. Star Tron breaks down this excess water and sludge to sub-micron size allowing it to be safely burned away during normal engine operation. Therefore Star Tron prevents phase separation and fuel gelling, eliminating ethanol fuel problems.
Star Tron Is Ideal For All Engines, Including:
ATVs, Cars, Trucks, Boats (2-cycle & 4-cycle), Lawn Mowers, Generator, Heavy Equipment, Snowmobiles, RVs, WeedEaters, Personal Watercraft, Diesel Engines

I purchased a 1989 Grady White Offshore 24 with a 2 stoke 225 HP Yamaha Excel. The boat was on the hard for maybe 2 years with full fuel tanks. I suspect the owner only ran off the main 95 gallon tank, and saved the 55 aux. tank for emergancy. Needless to say, I was lazy and just dropped her in and started using it. The (3) carbs got gummed up. The motor simply wouldn't idle and ran poorley at speed. Another Grady white owner turned me on to STAR TRON. 20 bucks, got nothing to loose....
