Re: Using Bottom Paint on Brass Propeller
I was talking to an old timer at my local Marine Supply house, he said a lot of people use bottom paint on their bronze props, and he added that he hasn't seen very many and certainly not enough ruined props to warrant concerns about using bottom paint on the prop. He believes that improper grounding or some other factor would be the cause of deterioration of the prop.
I am bay no means endorsing anything. My experience after 15 years of being a low budget sailor, and just slapping some bottom paint on the prop supports what he said. My prop polished up real nice. Also, important to mention that my prop shaft zinc is half gone each year. This year since I am just about finished with the install of a new motor, I did spring for a can of Petit. Wanted the prop to be in top condition in order to see how the pitch on the prop does with the increase of HP. Also, It will be interesting to see how the zinc does this year.
