Did I just blow an engine?
Took the catamaran back out today after doing some adjusting on the engine that was giving me issues yesterday. While testing to see if my problem was fixed the other engine began to start running rough. Not only was it running rough but it now blows black smoke when reved and even leaves a trail of oil in the water. Please tell me there are other possibilities then a toasted engine. It will still fire up and the oil pressure is steady and holding about 70psi. Oil looks clean and full

Black smoke is a ton rich. The extra unburnt fuel is leaving those marks in the water.
If carb'd - get the carb apart and see what is flooding it. Look at needle and seat first. Trash will stick that open.
FI - get it scanned / then if you havwe to ck fuel psi / ck for stuck open injectors.

Sounds to me like you need to step back for a second with this boat, and spend some time working on it, before taking it out again, and possibly doing permanent damage.
I would, do a full tuneup, plugs, wires, cap, rotor, fuel filters, etc. Go thru the carbs, check/set timing, . Then, go back out on the water.

I have done plugs, wires, cap, rotor, rebuilds on both carbs, complete fluid and filter changes all around and checked timing on both engines. The tanks were pretty nasty when drained the boat did sit untouched for 5 years. Debris is definitely possible.
