Hi, can anyone tell me how many and what size zincs I will need? Boat will be in saltwater full time.
Thanks!
P.s. the boat has v drives

Do you have IO’s or V-drives?

If the latter add zincs to each trim tab in addition to the others.
Then, hang a zinc fish off the stern when slipped.

I went as far as having a marine electrician come to my slip and test the water and surrounding area. Turned out the boat next to me was a battery and lightning up the hole pier. I lost a Bravo drive to electrolysis.

The shafts have zincs on them as well, and there is a large zinc attached to the transom.
 
I would say 1 1/4 shafts
R4 for the trim tabs
SR12 or SP50 for the transom
