Hello. My name is Tan.

Those are the drain plugs. They go in the side of the engine block. # ***** is the blue wing nut it screws into # ***** There should be a washer with the wing nuts also. http://www.marineengine.com/parts/mercury_marine_parts/static/img/COMMON/37731.gif

When you start the engine look for water leaks. There are more than 2 plugs on some engine so if you find water coming out of the engine that is where another plug needs to be put in or the hose reattached. Different mechanics winterize in different way so you might have more than those 2 plugs/wing nuts.

Thank you.....Tan
