anything i should add in the tank?

[fishingman220]

I winterized my boat last month, and now i finally have the money to fill up the (bottomless) tank. i have a 2bbl 5.7 with a 70 gal in floor aluminum tank. when winterized i shut the fuel off and ran it all out. is there anything i should put in the tank other than stabil????

Stabil should do it, just be swure to add the right amount.

With sta-bil in the tank you should be good. The only thing i would do different is keep treated fuel in the carbs.

with the 70 gallon tank, they sell a jug for 80 gallons i just put the whole thing in.

First -- You didn't run it all out! The carb does not go completely dry before the engine dies. Second -- add the fuel system treatment BEFORE you shut the engine down. This allows treated fuel to enter the carb and it then does not need to be drained.

for sure. I always add the stabil to the tank on the first day I go out and go "brr, kinda chilly today". since that means I have only a few more trips out. might be once more, might be many.
It allows the stabil to get all the way in to the carbs.

fishingman....not sure where you're located but if you have E10 in your tank, Stabil aint gonna cut it, you need to put something in to treat the Ethanol, either Star Tron or Stabil Marine Formula. Ethanol will separate out if not treated, and I would advise double treating.

70 gallons isn't that much fuel, so you should be able to treat it fairly easily. A bottle of Star Tron will treat a couple hundred gallons. The best way to treat Ethanol (E10) is to double treat and keep you tank full.

I dump a whole big bottle of Star Tron (they sell two sizes) I use the whole big bottle in my 250 gallon tank and keep it full for the winter.

I've posted this time and time again, Ethanol is not the same fuel you've been used to your whole life, you NEED to treat it the right way or you will have major problems. The ONLY way to treat Ethanol is to keep the tank full and double treat the fuel with a stabilzer made for Ethanol fuels, ie. Star Tron or Stabil Marine Formula.

I have also had manufacturers tell me that they suggest using a higher octane fuel in the Spring once you've run some fuel out, ie. if you have a tank of 87, after you run a bit out, fill it with 93, as Ethanol loses Octane while sitting and you may end up running you engine on 85 after a while of sitting, if you had a tank full of 87.
