I decided to dive and take the prop off to re apply Prop Speed protection. I brought the prop to a prop specialist and he told me I should get two years protection out of Prop Speed. Other people in my marina also tell me this. I get a maximum of 6 months protection before the barnacles take over.
The prop specialist said that I might have too much anode. This has a negative effect he said. I researched and came up with this (copied):
Repels Anti-Fouling and Propeller Coatings – in the same manner as paint blasting, over protection can lead to the non-retention of anti-fouling and propeller coatings due to in compatibility of the application with sacrificial anodes. This can render the application ineffective and the increased barnacle and other marine growths lead to vessel inefficiencies and costly manual maintenance.
Lure of Marine Growths – excessive cathodic protection accelerates the formation of calcareous deposits including the calcium carbonate coral-like structure commonly encountered on a vessel’s hull, rudders and propellers.
I have a big collar anode on the shaft, never knew about the micro size for the Beneteau mentioned.
Any thoughts or experiences anyone?
