Default Fuel polishing/tank cleaning westchester NY

Can anyone recommend tank cleaning in Westchester? Had my left carb rebuilt and the guy said it was pretty bad. It could be just because the carb was old, not sure. I run a 10 micron filter that I change annually and when I pour the fuel out it there’s not much crap in it at all, but might be a good idea to clean the tanks anyway. Thanks

Hey Greg,
I'm not really sure you need that service with gas engines. For at least a couple of reasons...
Tanks with gas in them stay cleaner than diesel tanks. Most of the "junk" that you find in diesel tanks are dead (and living) bacteria that live in some water in the tank, and feed on the diesel floating above. Diesel owners literally have to add "biocide" to the fuel, but the bugs can't do that in gasoline.
Also, the jets on a carburetor are much larger than the nozzles on a diesel fuel injector, so gas engines are much more forgiving of dirty fuel than compression ignition engines. Whatever gets by a 10 micron filter really should pass through a gas engine.

The "junk" that accumulates in the bowls of gas engines probably is from molecular amounts of water that the ethanol attracts into the gasoline, and deposits of "varnish" can form that can gunk up the jets and slow down the floats, etc, etc. , especially with underuse of your boat. Its a vicious cycle, but I think you just have to use your boat more!

I'm sure guys on here know more about this than I do, but I hope that helps.

Mike

There are DIY options that I’m considering, what size tank, how much fuel is in the tank?

Two tanks 110 gallons each side, but I'll let the gas get real low before I actually do the tank cleaning

Oh, glad to hear back and glad that was useful! Again, if your fuel filters look good, I think you are good to go... Maybe try to find some ethanol-free fuel in your area to stave off future carb trouble. My aviator friends are big on finding fuel and are always on top of stuff like that.

I tried to attach my DIY "fuel polishing" system. Not sure it uploaded. Its a neat little system to polish the fuel with easy to swap filters. I don't think you need this, again, but, its an idea...

If your thinking your carb was dirty because it was old tells me they have not been off in a while since you run your boat 3X per week every week, pull your 10 Micron filter at proper interval and it looks clean you should have minimum fuel issues. I think it was just time to clean your carb and since you run your tanks low often you should be picking up the crap in the bottom and if the 10 microns look good I think your tanks are fine.

The only reason I mentioned it is because the guy that did the rebuild said it was something I should be aware of that it appeared the tanks had a lot of crap in it. I change the filter every march, maybe I should do it twice a year? When I change it I check the filter and I dont get a lot of stuff at all in it which is why I was surprised when he said that.

It was definitely time clean the carb, as I've had the boat for 4 years and hasnt been done in my time haha. I usually dont run the tanks less than 1/4.
