Replacing the Magnesium (fresh water) anode on my DPS-A outdrive this year. I have recently repainted the outdrive this off season. Do I need to sand down to bare metal, to allow metal to metal contact between the bottom of the anode and the aluminum drive housing?

No. The bolts will make the necessary contact. You sand to bare metal it will corrode at that point
