Yes, beautiful Merc. 52-53s are my favourite. Mine has a stumble at take off which I attribute to a weak accelerator pump in the Holley carb. I've learned to live with it. Works fine at higher rpm. The Mercomatic seems pretty forgiving as mine is all original and still working. I'll have to check the label to see what oil I've been adding. I've read so many discussions here and elsewhere as to what is the proper oil that I can't remember what the consensus was.
