I would think the cold Winter start-ups the car has to endure would exacerbate the issue compared to the typical warm temperature a Winnipesaukee boat is going to enjoy at start up. My boat engine is probably already at least 65 degrees when I first start it up most days. It's never been started below 32 degrees. Yet, even though the car gets most of it's starts in cold weather (I ride a motorcycle when weather permits) it still works fine.

Mainly the reason cars are less affected is because they are used daily or at least a heck of a lot more than most boats where ethanol corrosion becomes an issue. This is why boats, snowmobiles, ATV's and any combustion engine that either gets stored or not run daily, ethanol corrosion becomes a real issue. The longer an engine sits that has used ethanol laced fuel the worse the problem becomes. The problem is not running the engine with ethanol the problem is when the engine is not running or stored after ethanol....
