I did check the crank for endplay and it was within the manual specs. Any reason I can't reuse the rings or should I replace those while I'm at it? I've got 100 psi even on each cylinder.

I had to add couple shims to keep everything aligned properly, using a feeler gauge of course.

The good news is no valve train to mess with, the bad news is everything is on lose roller bearings except the top and bottom bearings.
Keep track of the bearings and don't mix them if you can manage it. don't mix the shims in the sides of the piston pins or anything else like that.
If you don't have a manual buy a Mercury Factory service manual, it's worth every penny.
Pay close attention to the water tube.
Expect to break a few bolts, heat is your friend!

Thanks! it turned out pretty decent, If you turn up the volume though you can hear the knocking, One more time in the test tank with the stethoscope and I think she's coming back apart for diagnosis. Hopefully the crank isn't buggered up. 100psi on every piston so I'm not happy about tearing it down.

Any advice on pulling the crank and rods is more than welcome. I'm used to plain old detroit V8's so this is a bit of a different animal for me.

You're close! I get a message that the video is "private". There's something you need to click in YouTube to allow anyone to watch the video.

I believe the way most videos are "attached" is to post it to YouTube, then insert the YouTube link here.
