Engine Ground Bolt Location 4.3l mercruiser

[Blithering Idiot]

I've been a boat owner for 32 days and have a (I think) simple question.

The largest black (negative) wire coming from the battery has become disconnected from its' destination. Looking around on line it looks like it likely goes to an engine ground bolt?, but I cannot find it.

Originally I thought it connected to the starter, but I found a diagram that shows otherwise.

Help is appreciated.

B.I.

Can you trace the black wire going to you slave solonoid, the battery and solonoid black should go to the engine bolt

There is usually a stud sticking out on both port and starboard sides of the engine bellhousing used for grounding. Both the main grounds from the battery and the factory engine harness are connected to them.

might be dumb question...but if this ground location is corroded, could that be a possible factor to my boat intermittently shutting off usually under load-like maybe the extra voltage draw is being restricted from corrosion?
