I’m looking into replacing the Has anyone taken a stab at swapping out the black tank and pump with this setup,
…if so what were the good the bad and the ugly(other than the cost)

Thank you in advance for any feedback!

Is the current tank leaking?

But the actual swap is extremely easy and straight forward - there's really nothing to worry about. I imagine the hardest thing is going to be, like with most things boat-related, the access. And, that, I can't help with... I'm too far away :)

No, but my pump is out and I hate that system, seems like everyone I know with a Grady is constantly messing with it! I don’t plan to pump out very often so it isn’t a huge deal but I like systems that work when needed

Can you just adapt your current tank to use an external mac? You just need to use a dip tube... or use a Y-valve in your pump-out deck fitting's hose to select overboard or pump out.
 
I reworked mine. Using silicone hoses make it easier to take something apart if something goes wrong. If you are going to do this don't mount the macerator vertically - go horizontal like the one you put up. These pumps don't like to "lift" and the impellers will dry out and loose prime if not used often. I have to take my pump output hose off and put some water in it at the beginning of the season. Setting it up horizontally helps keep it wet.

Also consider access to the tank, retainer clip/screws and hose removal/reinstall. Also dimensions. If there is nothing wrong with the tank I wouldn't attempt to get it out. Clean it out well when the Groco is out. Make a starboard cover and 5200 it down. Make the pickup tube out of PVC.

Might be easier to swap the macerator and use the existing tank (if the same - looks like mine), the wiring and controls if working.
 
I have no power to my waste tank, 2009 Chesapeake. The manual indicated a separate breaker for the head, and the waste tank macerator. However on my panel there is no separate breaker for the macerator. Can anybody provide a little guidance? Thanks

Probably a fuse. My pumpout panel has a fuse holder on it. You may have one behind the panel. Also all the 12VDC circuits that are not switched are fed off a fuse block (mine is under the helm).
 
It doesn't show on the electrical plans, and for some reason I'm not getting power to my head now also. Is there a relay? It should be a direct line to the breaker? The breaker reads 12 volts on the output screws, but zilch at the head. WTH
