That kind of surface corrosion is pretty normal for a bronze shaft, especially inside the boat. Exactly where are you seeing a zinc in this photo. Zincs are normally on the exterior portion of the shaft, as the need to be immersed in water to function properly. Occasionally, you'll see one on a shaft inside the boat, but that is generally as a safety measure, so the prop shaft can't fall out....but not to prevent corrosion.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
