Whaler Central - Boston Whaler Boat Information and Photos

I have a 25' Revenge that I recently bought with apporx. 60 gals of old gas in tank for about 3 years. The boat is on stands. I know I need to add a tank cleaner, is there one that is better than others? How does this get worked around the tank? Will all the fuel hoses need to be repalced?

I am assuming the gas was treated with a stablizer since it was last witerized by a marina.

Scubadog,

Congratulations on your purchase. Now the fun begins.

I would strongly recommend you remove all the gas, or at the very least, draw off a gallon into a glass container and let it sit for a few hours. If the gas has been sitting for 3 years, even if it had initially been treated, it is likely in bad shape.

I went through the same last year. There was 30 gallons of gas that had been sitting for 2 years. It had started to go through phase separation.

I would also recommend you examine your fuel hoses and look to replace them all.

X2 themclos. Additionally, I'd replace the fuel filter and run Seafoam through the engine once you have fresh fuel in the system.

Yep, I'd certainly dispose of the fuel one way or another. I hope you have a lot of ATV's, lawn mowers and edgers to burn all that fuel in! Lol.

Scubadog -

Get all of that gas out of there! I know from unfortunate personal experience that no additive can fix old gas especially now that it contains ethanol. If you can also purge your fuel line-- do that as well. Then add fresh gas along with something like Sta-bil. I was able to go to our local landfil that has a household hazardous waste program and dump the old gas. Don't put that gas in anything else unless you don't want it to run. Seriously, I KNOW from experience. :-)

Best of luck to you--

I had a similar problem when I bought my Montauk, had about 18 gallons of nasty old pre-mix. Scratched my head, figured one man's trash could be somebody else's treasure and put an ad on Craigslist for free gas. Didn't take 15 minutes and had it all gone. Keep in mind, the kind of people who like free old gas may not be the kind of folks you'd like coming to your house.

Gasoline will begin to degrade in just 30 days even WITH fuel stabilizer in it. Rule #1: "Always start with fresh fuel", I'd change out the hoses, filters, and run sea foam through the system as well. I've been using "Sea Foam" every time I add fuel. I saw it recommended by many members here on W/C, and it REALLY works !

What kind of prejudicial BS is this? I've got several pieces of old farm equipment that still perform hard work when needed, and they run fine on old gas. I guess that makes me undesirable?

scubadog, I agree you should siphon the old gas out. If I lived near you I'd ask you politely for a few gallons to fill up my tractor.

A bit sensitive aren't you? But yes, I can honestly state that I do not "desire" you.
