[C320-list] Prop and shaft barnacles

[Utility Email]

I researched this extensively years ago and concluded that zinc rich paint was the way to go.  So far it has worked very week for our boat when we were in San Diego and also now in the Puget Sound.  I clean up the stainless steel propellor shaft and bronze propellor and shaft strut.  Paint all of it with several coats of zinc rich primer by Petit taking care to mask off the areas where I install zincs.  Install zincs and I am good to go.  Not much marine growth on the prop, shaft or strut.  The can of Petit primer is about $20.

I do not dive and clean the prop at the dock as we are on the fresh side of brackish water and I worry about stray electrical current. For some reason, now that I am eligible for social security, it seems to take me longer than it used to... I’m thinking about buying a tank.
