Location: Forest Lake, Mn. | I have a 2005, 90 Yamaha 4 stroke and a 15 Yamaha 4 stroke kicker. I also live in Mn. The 90 is direct injected.
I use Seafoam in every tank of gas. I also have a fuel-water seperator filter in the boat. I didn't properly winterize my rig last year. Paid the price. Had to have the carbs on the kicker rebuilt this year. It won't happen again.
Other than that, I haven't had a problem with either motor due to ethanol gas. My owners manual for both motors state that up to 10% ethanol is ok for use. As long as you use something like Seafoam or Stabil and add a fuel-water filter. I don't think you'd have much problems.
After all, if ethanol was causing major engine damage to a large number of newer motors the motor companies would be screaming due to the warrenty repairs they'd have to make. or dealing with the PR nightmare they'd endure because of it. Nobody would buy their motors. It's cheaper in the long run to build a motor that will run on ethanol in my opinion.
I had a 92, Merc 40 horse 2-stroke. I had lots of issues with that motor and ethanol gas. Ended up with a cracked block. It's to long of a story to post.
