Water pouring out of exhaust

I rebuilt a Mercury 1150 (1976-1978.) I got it running, but noticed water pours out the exhaust. I assumed that I ripped the powerhead to lower unit gasket, so I replaced it. Water still pours out the exhaust. It's possible I ripped the second one too, because I forgot that I have to get the nuts started on the studs before lowering it all the way. I'm going to try and replace it again, but I'm wondering-- the only other place it could leak out of is the exhaust baffle plate, right?

Also, when I went to change the powerhead to lower unit (or exhaust extension plate) gasket, there was a watery sludge in the driveshaft chamber. I'm assuming it has to be that gasket, because that's where all three places have a chance to meet. Unless, is it possible that waters getting in the exhaust through the baffle plate (I never touched the water jacket-- not sure what it's there for) and leaking down into the cylinders and down the crankshaft, through the lower end cap and into the chamber where the driveshaft is located? That's impossible right?

Both the exhaust and cooling water from the engine exit through the center of the prop. Make sure you have a tell stream coming out the cover usually just below the power head and you should be good to go, Another thing you can check is for water in the lower unit gear case but I doubt you will find any. If water is just coming out the prop you should be good to go.
