I've got a 1979 Silverton with Chrylser M360B engines and Carter 4bbls. The
gas tank is aluminum, so that shouldn't be a problem. The fuel hoses can be
replaced easily enough. However, has anyone had experience or know whether
engines this old will run OK on 10% ethanol fuel? Will I have to mod the
carbs?

The main problem with ethanol in marine use is that alcohol attracts
water. So if your boat sits in the water at a marina I would avoid
anything with ethanol. If you are trailering then I would recomend
either leaving the tank as empty as possible or keeping it full. A
half full tank will collect the most water because the fuel will expand
and contract with temp changes and you have a lot of space for humid
air to be in the tank.

Nah, it will run fine. But, as someone else pointed out, ethanol is
basically dry gas and absorbs water. In vented marine tanks, just humidity
will introduce water. So, use the boat often to limit the amount of time
the gas sits in the tank(s).

I am driving some old cars around ... 60's vintage. They run fine on the 10%
ethanol. In fact, the '67 GTO used to ping a little on the old high test,
but the new ethanol blend high test seems to have eliminated that. (ethanol
boosts the octane).

Because I don't drive them daily, I only put about 5-6 gals of gas in them
at a time so it is reasonably fresh when I do take them out for a spin.

I burn 10% ethanol in my 3.0 with no problems, but every other fill up
I throw in a bottle of HEET.

Don't know if it helps, but can't hurt....

Heet is primarily isopropanol alcohol. Ethanol is also a form of alcohol
(grain alcohol). Generic "Dry Gas" is ethanol based.

Basically, they all do the same thing, so you wasting your money unless it
gives you peace of mind.

I bought two cases of the stuff for next to nothing at an auction,.

So!.......
