Just wondering if carburetor flange can handle pulling motor ? Or need to used longer bolts corner to corner on intake ? It’s 7.4 and it will have manifolds still on but not risers . Seems to be leaking at y pipe flangeWater dripping onto power trim lines. Anything visual I can see it’s not leaking . Steering shaft, water inlet ,Back motor , transom bracket . I even put 4200 around transom ,change powertrim manifold gasket , and resealed mecartrode o ring. Got to be inside bilge. I’ll know more after get motor out.
 
In this picture it looks like the thermostat housing and intake manifold are where the lifting points are located. I also had a leaking Y pipe flange. I think you're going the right direction. It was almost impossible to see, but after sealing everything else, that was the only thing left.

If it's the Y pipe it will leak on the flusher in the driveway. So if it doesn't leak on the flusher, that's not your leak.
I have a steel plate that I bolt to the intake manifold with 4/ 1/4" bolts for lifting big blocks
 
At least a foot above that. I've had good luck finding leaks by jacking up the trailer tongue very high and filling the bilge with water to just below the starter.
