We are launching our boat sometime next year & I have a question about antifouling relating to inside the stern tube & the propeller shaft inside the stern tube.
Not having any experience with this before I was wondering if anyone had any ideas on the subject, if it is necessary or not.
I agree, don't do it. No gain but much hassle. I've pulled many stern tubes & shafts over the years & have never had a issue with fouling. Painting does have the potential to block up any water lube ports for mechanical seals etc. which would be bad.
