I did try turning the distributor both ways as far as it would go until it nearly killed the engine, and the rpm would change a little, but still ran rough.

Quick question, do these have a timing advance that needs to be unplugged while checking the timing like an automotive engine?
what year?

Ok, I'll have to recheck my timing. I'm positive that it still isn't the root cause as I have turned the distributor as far as I could both ways and the miss never cleared up.

i'm gonna get the dunce hat for this one, but i think it's the gasket.

in video 1 water is coming from the propellor hub and transom assembly bypass. as it should out of the box

in video 2 alot of water is coming from the bypass on the transom assembly, and none from the prop hub.

on stock mercruiser ex manifolds water mixes w/ exhaust gas right at the end of the riser around it's perimeter,

the new gasket flows more water since you said the riser is cold
if more water got introduced into the exhaust couldn't it be sucking some back into the engine causing it to run rough,

Be easy enough to check, pull your dipstick

You might be right.
