My question is that in the North East, is it really necessary to paint the prop and shaft with the special anti-fouling paint?

Right now, I have prop and shaft all polished and cleaned.
Thanks

I used PropSpeed paint on my prop. It is very expensive but a year latter i did bottom cleaning and all I had to do i wipe it with a piece of carpet. Prop is the only exposed metal in water aside for 25mm of prop shaft. I changed zinc even though there was more than 75% left because it was covered by barnacles.
I would use PropSpeed again

I second the Petit product.  I have used it for a number of years and had no barnacle attachment.  A friend in a neighboring marina had so many barnacles on his after only 6 weeks in the water
