I was working on a friend's boat (Mercruiser 4.3 LX Gen+) and noticed when installing a new starter and the blue drain plugs on the starboard side that he has a bolt missing from the block and someone had caulked the bolt hole closed at some point. The caulk did not hold up and I think it allowed some water inside.
I was unable to find a schematic showing me a part number for this bolt. Can anyone tell me the part number or size & thread pitch of this bolt (see picture). Thanks for any help!
