I run the boat untill about a 1/4 of tank of fuel then i disconnect the fuel line at the filter connect an elecrtic fuel pump from a car or boat pump and pump the remaining fuel into my truck.real easy and nothing to worry about next season.

Works great with Ethanol. Never had luck with Stabil.

How would one go about pumping out every last bit of fuel for the winter........I would think there will always be something left in the tank and in the fuel system.........I am extra nervousbecause I run twin Merc 575 SCI'S which require a minimum of 93 octane...............What to do......What to do.....


575sci's only require 91 octane. If you fill with 93 octane you should be fine. The octane will probably drop to around 90-91 over a 6 month storage. You can also leave room in the tank and add 5-10 gallons of 110 octane in the spring.

I've bought it from both Overtons and BoatersWorld- I just did a search on their sites and don't see it listed!

After a quick 'google', I found this site that has it, (weird- it's some kind of survival preparedness outfit), and I have to admit their prices are several dollars less than where I'd been buying it. They even have it available in quarts and gallons.
If you have diesel truck (or boat) their PRI-D product is just as good as the PRI-G is for gasoline.

Top off the tank each fall (late Oct. to early Nov.), treat with the proper amount of Sta-Bil, and next spring (usually bust her out in late March to early April) she runs like a top. Never had a problem with E-10 drawing a bunch of moisture or dropping octane to the point where the motor knocks.

Ditto. Never any problems either. And if anyone is concerned about a slight drop in octane just top it off in the spring with a higher grade and you are good to go.

Sounds like a plan...................

I leave my 55 gallon tank half full with 91 octane with sta-bil between sept thru april.In the spring I'll add 5 gallons of 114 octane from my race car reserve and the rest 91 octane pump gas.Been doing this for 10 years and no issues.

I should have added that I do top off the tank in fall with either 89 or 91 octane gas to compensate for any drop in octane that may occur. My motor (496) only requires 87 octane.

In the past I usually left tank at 1/2 or less, rarely used stabile, then filled up in spring before running. Figured I diluted the bad w/ the good. After running that tank thru I normally changed the plugs (carb engines) for the season.

Not sure what I'll do this year.
