Just picked up a 98 353. Never had a boat w/sink. RV fluid coming out. how do I de-winterize it?
thanks

fill the water tank with water, turn on the faucet....congrats, your done!!

I usually add a couple drops of bleach per gallon to keep the water fresh longer (I don't drink it)

I drain the tank, and then add 4 oz of bleach to 1 gallon of water. Let sit a couple of hours. Drain, add clean water and drain again (from all faucets and showers at the same time). Fill.

This usually does it. If there is any bleach taste, add a little white vinegar.

Like already stated, flush it multiple time first to get all the antifreeze out. I add stuff called TastePURE (1 cap to 10 gallons) purchased at a RV store. Keeps the water fresh tasting and odor free.

Also got a TastePURE carbon water filter that goes on the end of the hose for when we fill up at our dock. The water there has a chlorine taste and this removes the chlorine.

I wouldn't use bleach as it won't be good for the hoses over time. If it is just this once then it would be fine. Otherwise Westmarine has a product HERE
