Sea Foam has no alcohol.
No
This has been put out before.
Sea Foam is purely a petroleum based product. I bought a few cans and use it in my boat, lawnmower, car, etc. I bought it after reading a bunch of non-Sea Foam sponsored reviews which indicate it works.
You can find them on line.
Just took a look at the can. Sea Foam is a 100% pure petroleum based product.
Check out the feedback from folks who have used it and you may find some useful info. I don't put much stock in feedback from the companies, so I look for places that have reports from users.
I have a Johnson 48 spl that would clog up on me most years. It was living in a high humid swamp area of South Louisiana for months at a time. After paying for carb cleaning a couple of times a Cajun outboard mechanic told me to get some Sierra Carbon Free and spray it everywhere I could think of in the carbs. I'd pull the float chamber drains and spray some in and close the drains, high speed jets, air intake to drip, etc. Then let it sit overnight and the next day, it ran great.
Last year, I started adding some Sea Foam to the fuel. I'll know in a couple months or so how it did. In any case, the Carbon Free worked like a charm.
