Really bad idea from a safety point of view.

I never run the engine dry except at winter (seasonal) storage time. I treat ALL my gas for my dinghy engine, lawnmower, snow blower, etc. with Stabil. Never had a problem.
We have had only ethanol gas for many years around here (Ct).

Just a thought...


Yep. I picked up a couple spare fuel fittings, so I can stick one of those on the end of a disconnected fuel hose so it'll drain on my 3-week schedule. And when winterizing.

Nope...not a joke. 2 gallons of gasoline in a 100 gallon+ tank is not going to affect much of anything. Now, I have never done it. But I did start a thread awhile back about what people do with old dinghy gas and quite a few on here made this suggestion. So search for that thread.

Edit:I went and read that thread. Only one suggestion of putting it in boat. The rest said to put it in car. I'm getting old and forgetful!

Like any debate, there are always at least two schools of thought that can be put forward. I have found in the past that the "varnish" in the carb is the result of gasoline drying out and leaving a deposite. (Varnish) This doesn't seem to happen when storing your motor "wet."

We take our dink motor off and it lays down, so we run out the fuel so it doesn't leak all over the deck, but we do use it alot and have no issues.

We use Staybil 360 for lawn mowers, snow blowers and classic car, no issue there either.

Oars don't mind ethanol , unless you drink it.

WE have a Grumman Aluminum sailing dink and can visit harbors , near the shore , and no one throws rocks for the wake or stench.

With fenders lashed inside it does double duty as self rescuing life boat offshore.

I read on a thread on here that gas added to the diesel tank would prevent algae growth. I think it was 10 gallons gas to 200 gallons diesel.

Algae does not grow in diesel fuel. Algae needs light to grow. What grows in diesel (and jet) fuel are bacteria and other micro-organisms. These micro-organisms tend to live at the water/fuel interface in the tanks, living in the water and feeding on the fuel as I understand it.

There are a number of biocides available as fuel additives to prevent this growth or kill it if it has occurred. One of the most popular in this area with boaters is Hammond's Biobor JF.

When storing for any amount of time I use 100LL aviation fuel, generators, boat motors, chain saws, motorcycles. Add a gal or less, start turn off gas or let it run out depending on the type of fuel system.

Been doing this for over 20 years now and never had a problem with any equipment. Airplanes sit for a long time and you never hear of av-gas going bad. 100LL will even clean out the crap left from auto gas.

You can purchase it at any FBO at your local airport, here we even have gas stations that sell it due to all the air-boats that use it.

When it evaporates it does so clean like naphthalene or vodka, 5 gals will take care of everything. My dingy has 3 gal of it right now.

Not for use with a catalytic converter as it has lead in it of course.

Just be sure the bottom of your dinghy doesn't drop away, sending the battery as deep as the motor-battery cable is long.

With Ray at the oars, there's no need for a mechanical engine.

I always purchase non-ethanol gas for use in my 20hp Honda outboard. I use Stabil every time i purchase gas. I generally run the engine dry if not using it for more than a week or two, but sometimes I forget. Either way, it always starts.
