Re: [OMC-Boats] Crankshaft area now?

Did you pull both heads?  Can't be too sure where a noise might be coming from.
 
In anycase, yes, if you drop the oil pan you will be able to see everything you need to see to determine where the noise is coming from.  Could be a bolt droppedout and is rattleing around, etc.  Could be a bad bearing that is allowing crankshaft movement.  I had that happen on an '86 station wagon I bought at auction.  Sounded pretty bad when it warmed up.  Ended up swapping out the engine.
 
I'm looking forward to the results.

I found what making the engine rattling noise - it was just a penny that some had left in the cylinder by accident (see photo)!!

Ok just kidding.  Nope didn't find anything in the port side - the side that's making the noise.  Grrrrrr.

So looking at the exploded diagram, it looks like the only other "void" left to check is down with the crankshaft stuff.
But seriously, if one of those bolts down there worked loose, I wouldn't even be able to start the engine would I? And/or wouldn't it just fall down into the bottom of the oil pan?

If I pull the engine out and take off the oil pan, am I gonna be able to see all the crankshaft guts?   Thanks!
