Speaking of barnacles on the prop...
I dove down and checked my prop again and found that in the 2 or 3 weeks since last posting here I have grown a new colony of barnacles. Smaller to be sure but they are there. I have a MaxProp and it is bronze. Last year I did nothing to it and I don't remember having much problem (last year was my first full season with the boat). This year I sprayed the prop with some Zinc spray from Pettit that the PO left in a box of odds and ends.
So what do you all use on the prop?
