Well that's nice for new equipment...but we don't all have new equipment. :/

A point Mr. D'Anniballe acknowledged in the story.

Great for the industry, bad for the owner of existing technology, unless the retrofit is reasonably priced.

i don't think that "cheap" will be the case for the retrofit if you decide to set your boat up for e-fuel. unfortunately when you mention the word boat (break out another thousand), that's what comes to mind. e-fuel is simply a BAD deal all the way around

Right, but swapping fuel tanks isn't easy. The rest didn't seem awful.

Maybe should start a different thread but what exactly would need to be changed in say a HP500EFI or 525?

You make an excellent point. Even fuel lines with Teflon inside aren't that expensive. But replacing fuel tanks? Big expensive job—if even feasible in the first place.

Mr. D'Anniballe called me with his perspective, and I want people to have another point of view from a credible source minus all the political debate that took over the last story thread. It isn't that the discussion was bad—I learned quite a bit—but it morphed into something that strayed a bit off topic.

Matt, sorry for sounding snarky, I was posting from my phone.

The tanks are the only issue raised in the article that are beyond a normal boater, IMO. SS tube and fittings are not cheap, but they are shiny and thus we boaters will gladly purchase them. Aside from the tank, I'd think $2000-$3000 would get you ethanol ready. Couple hundred for a fuel pump, another couple for hoses/fittings, and then a tune. Of course, the cost of the last part could vary wildly.

One could probably coat an AL tank in situ to mitigate corrosion, but the fill hose would be a challenge, and I'm nearly certain it won't be economical.

I read nothing snarky in your tone. Your raise legitimate concerns.
