Is the aluminum of the outdrive casing corroding? Or are the zinc's corroding?
The most common location for drive corrosion is along the thin spots, like the edge of the anti-ventilation plate and the skeg.
Zinc's are supposed to corrode. If they corrode beyond 50%, I change them. You might simply have a higher change rate than normal. If that is the case and you are in freshwater, then I would be looking for stray current at the dock.
Is this boat stored in the water or on land?
