This is my first post and also my first boat. Very much impressed so far and put on 65
hours this summer starting July first.

My boat has a 5.7 lt engine. Today when I began searching for the engine drain plugs
(blue in color) I located Port Side, from cylinder block and bottom of the exhaust manifold.

On the starboard side I located the y-fitting drain plug and also disconnected the red (hot hose) which I gather is the cylinder block drain as there is no plug in that spot due to plumbing.

I removed the four rubber hoses from the cooling system and drained as much water out of them by bending them over.


My question is, I helped another boater winterize his 5.7 lt. Year not known although also Merc Cruiser. He had five blue plugs. Now I realize in actuality I removed four when considering the hot water line. Have I missed a plug, and if so where will I find it?

In my owners manual someone has used it as a guild prior to my owning the boat. They have placed a question mark on C- water tube drain plug located on the Port side of the engine.

If you know, email me directly, I?d appreciate it!!

Thanks!
