The drain plugs are blue plastic wing items. Go to the Documents tab of this site to find the Mercruiser manual for your engine to locate them.
Typically they are on the lower water supply elbow to each exhaust manifold, lower mid section of the engine block just above the oil pan line, one one the power steering cooler. If you have a Bravo drive the inboard raw water pump may have one as well.
