I've got a seep from the gasket at the base of the powerhead. I'm going to lift the powerhead off this winter and change the gasket. Has anyone ever done this ? And is there anything else I should do while I'm in there ? Does the exhaust lift out of the intermediate housing? Thanks

If its just been in fresh water then you can probably get the bolts out without breaking them. The exhaust stays inside the stack and it will split clean at the seam.

should I pull the exhaust and clean out any water ports? Is there more than one gasket? Thanks for your help.

Nope, don't try to disassemble any of the exhaust housing. I will be surprised if you don't find a bad place in the mating surface that allowed the gasket to blow out.
