So I've always heard the whole don't use ethenol it'll ruin everything story. Eat the gaskets. Kill the fuel line/primer. Etc. Countless times told to only use 100%. I've had my main boat for several years at this point. It's just running a 1993 70hp Johnson. Fresh rebuild when I got it. And for a time I stuck to 100% gas. But shortly after I switched to just ethenol pump 87. And still everything is tip top. No carburetor issues. No fuel line issues. Runs just as good as the day I got it. I've even let the boat sit months at a time over winter and every spring it always fires right up and runs perfect. I pulled the carbs apart this last spring because i was giving the whole engine a full health check up and all the gaskets looked great. So I'm just wondering has anyone here actually seen or had ethenol gas cause any harm? or is it just a superstition? Unless when this engine was rebuilt the gaskets and seals used were better suited for ethenol use than the OEM stuff. Is that a thing?
