I have a 1994 merc black max 150hp, the swivel bracket is extremely stiff. anyone have any ideas how to loosen it up, have added new grease/ heated tube with torch, and it still is real stiff.

See if grease is exiting the top part of the swivel bracket. Probably not, which means the top bushing is dirty or corroded.

When I had this issue on my '93 Merc V6, I tied a rope around the lower unit and the swivel bracket, and twisted it like a tourniquet to make it tight. With the motor tilted all the way up, I was able to lift the motor a bit to allow grease to more easily exit the top bushing.

It is probably not a permanent fix like disassembly, but it is working for 2 years so far.
