Does any one know what I can or even where to dispose of last years gas which is still left in my tank...I have read what it is not good to hold gas for more then 6 months ... I have an 8 cylinder o/b on my Catalina 25 and I have close to a full tank

I waited until the tank in my truck was nearly empty, dumped the remainder of my boat fuel in the truck tank and filled the truck the rest of the way with fresh gas. No problems.

Next year add some gas stabilizer to the tank before storing for the winter and you will be good to go in the spring. For now the truck idea will work fine or you can mix a little of it with with each tank of gas on the boat until it is all used up.

Similar strategy here with the riding mower. Since we have multiple tanks, we just make sure at least one is empty at the end of the season. The other is relegated to Lawnmower duty for the Fall/spring until empty, or very close.

At the end of the season we dsconnect the fuel hose and let the outboard run dry. Then we put the remaining gas from the tank into the lawn mower.

Randy,
there have been several discussions surrounding letting the bowl run dry, and I'm not certain about it, but it could leave gummy deposits in the carburetor, especially if your carb has very fine orifices in it.

A friend suggested I fill the bowl with Coleman fuel or white gas and let that run until the bowl is dry. According to him, Coleman white gas is very thoroughly refined.

Since I don't have a fixed gas tank on Passage, when I button her up in the fall, I disconnect the gas line, spray in carb cleaner, remove the engine and pull the tank.

I add the 3-5 gallons of gas remaining in the tank into my Jeep gas tank. No point keeping that stuff around all winter.

I also empty the fuel-water separator in the fall. If there's any water in there, I don't use the gas, and just burn it off in my outdoor fireplace.

Don't count on stabilizer to keep you gas ok for months off season. You may be lucky get by, but you are very likely to be bitten. If your fuel is exposed to enough temperature changes and humidity, it will phase separate and give you a dead engine with a bowl full of acidic fluid.

Thanks for the tip Bruce. To be honest with you we have had Hondas (8HP and 9.9HP) for the past ten years and have never done anything special with them and they always fire up in the spring. Disconnecting the fuel hose and running the OB dry is as sophisticated as we have gotten.

I do change the oil, gear oil, fuel filter, and spark plugs every spring.

That's about all any modern outboard asks for. As for emptying the bowl, since there are adherents on both sides and either approach seems to work, do what ever allays you particular anxieties.

I've been one of the "adherents" to the "other side", because a Honda tech told me, for winter storage in this E-10 age, not to run the carb dry. Rather, using fresh fuel with an double-dose of stabilizer, run the engine so the carb is full of the stabilized gas, and then shut it off and do the normal fogging. He maintained that the heavily stabilized gas in the carb was better over time than the film that would turn to varnish in the "dry" carb. The stabilizer labels I've read say there's no danger from an overdose.

I'm just reporting what I've been told and have read... and have done. My Honda 8 on Passage, my current Honda 2 dinghy kicker, and my injected 225 hp V6 Honda on Sarge, have all started instantly and run perfectly the following spring. BTW, I use stabilizer all year long in every tank of gas, as recommended by the same source (and others).

I don't keep the kicker gas in the tank--it goes into my Highlander, which has never noticed. The gas in Sarge is a more complicated issue--a topic for other forums...

Naptha (coleman fuel) is very volatile and can also cause damage. I do not know that it actually makes things cleaner by runnin git through your carb.

As a side note, when our MSR stoves gum up from burning coleman fuel through them, we put a couple tablespoons of carb cleaner in the tank to clean out the jets in the stove. Sounds to me like you could just skip the coleman fuel step and get the same results.

Cranked up my Honda today, hasn't been run in about 5 months and it's been a rough winter at the lake. Started up like always and ran great. I put stabilizer in the tank every time I fill up, I guess I've filled the tank maybe 3 times in 4 years.

With motoring through Destin harbor, a longish run down the channel to the gulf, and a long and winding channel to Choctawhatchee Bay, I have used 4 gallons of gas in 2 months. I don't know how much my son used in the snowblower at home.

I syphon it into the tank of my Denali. I have an old Evinrude 2 stroke and the oil helps the Denali run smoother. Of course the Yukon is old, too. I wouldn't do it with my wife's. Ity would probably throw up or throw a tantrum. IT is new, whyich is why mine is old, duh...

I have an 8 hp 2-stroke Suzuki. I always run the carb dry. Last time I ran it was in late October or early November. Went down to the boat a week or so ago and it started on the 3rd or 4th pull. Just my 2 cents worth!
