Moyer Marine should be able to spec that.

I need to drain the coolant from my Universal M4-30.  The drain plug in the photo I have from the manual is near the dip stick on the side of the engine I can reach but can’t see.  The photo in the manual is pretty useless as I can’t see what it is pointing to.  Does anyone know more precisely what it looks like (size?) or a way to find it by feel (or another way to drain)?  Thanks- Dave
