Gas expert wanted

[4fishing]

Boat has been sitting for a year with full tank (18 gal.) 2 cans of seafoam mixed in, through winter, snow and ice here from Nov-April

Q: drain the gas? thank you

 

[ahicks]

My vote: Run it!

 

[JASinIL2006]

Smell the gas. If it still smells like gasoline and not turpentine, run it!

 

[roffey]

I second the run it....

Ayuh,...... Welcome Aboard,..... The gas in the tank will be fine,......

The gas in the carb, pump, lines, 'n filter should be Ok,......

Volume helps gas keep longer,......
In my experience, a teaspoon of gas rots quicker than a gallon of gas, especially the gas of today, vs: the gas of the '60s,.....

 

[QBhoy]

Be fine.

Just picked up a 21' Sylvan, was told its been sitting 3.5 years. 3/4 tank in each tank. Took a chance and hit the igniter switch,,, started right up! You should have no issues.

Siphon or pump a few cups out into a. Clear container and look at it if its full of water or rust or wrong you should not run it through your carb.

 

[Scott Danforth]

sample the fuel in a clear container

you may be OK, you may have 18 gallons of toxic waste to dispose of.

If it looks like gas & its smells like gas it must be gas, my vote is run it!

My only concern would be the excess amount of sea foam in there. That stuff is mostly alcohol and burns hot. I would drain half into 2 5 gallon containers, top it off with fresh high octane to dilute the sea foam. When that tank is empty, repeat.

Always been told: "If it looks like Miller Lite then you should be all right, if it looks like Guinness Stout you need to flush that nasty *** out!"

Seafoam is less than 25 percent Isopropanol .You will have a nice clean fuel system for sure.For cleaning a fuel system seafoam recommends 2 ounces per gallon so your basically right on with 2 cans for 18 gallons .https://seafoamsales.com/knowledge-base/how-to-use-sea-foam-in-fuel/
