I drop a sta-dri water cell into the fuel tank and it absorbs the water. Check it every once and a while to make sure it hasn’t swelled up too much and you should be good to go. You can buy it from any snowmobile dealer for less than $15. I prefer to stay away from any additives when running a turbo.
You may want to look up Seafoam, it is used is used to absorb water in lines also, and as stated above, NEVER use menthyl hydrate. It is TOO dry, and will cause a melt down in some conditions.
