I have a PD 32 and I would never go back to a regular outboard. But I need that type motor. I run in the weeds, mud and shallows that will kill a water cooled outboard in short order. If the water was clean enough I would still be running my old 20 Johnson. I guess what I'm trying to say is if you run in the muck and mud then nothing will take the place of a good mud motor. But if you don't really need one get the Mercury.
