the plug should be 1/2" NPT (U.S. standard).

Need to find out if my boat requires a drain plug put in prior to putting in the water?

All boats have a drain plug that can be removed to allow any water that may have gotten into the bilge to drain out. It will be located low on the stern.

Some take a threaded plug while others take a stopped style. What year model do you have?

Yes you need to put the drain plug in before putting boat in the water
