Caleb Davison All Messages By This Member #9480 Ron, The zinc prop nut is the most practical solution to anodizing your boat.? Many sailboats have exposed shaft and a strut that they can apply a collar type zinc to but with the T27 that is not an option since there is minimal shaft protruding from the cutlass bearing.? A zinc nut holding the shaft on is kind of an ideal solution.? Instead, on my boat I lengthened the shaft by about 3/4" and then had room to place an off the shelf zinc collar on the shaft snug up with the propellor and deadwood around the cutlass.? Prop guidlines suggest that a prop not be suspended more than the shaft diameter in distance from the hull or strut. I remember having trouble sourcing a zinc prop nut for my setup but I probably could have done it that way when I replaced the old shaft with a new SS one that was threaded at the taper ten years or so ago.

Ronny Crisco All Messages By This Member #9490 Hi , thx for reply , however, only semantics , but a zinc nut would waste away promptly . The s/s prop nut not only holds the prop on , but also holds the bracket to which the prop nut zinc anode is attached.????????? Ron? S/V Hygelig

Ronny Crisco All Messages By This Member #9492 Hi !????? Note :?? There cannot be any such thing as a zinc prop nut. The prop would be lost right away !? However, a " prop nut anode "? is attached by a bracket held on by the s/s prop nut.? Btw, these are hard to come by here in the Philippines !??????????? Ron? S/V Hygelig
Brian Stannard All Messages By This Member #9494 Bronze carrier and zinc anode but it doesn't replace the propeller nut, is in addition to it. toggle quoted message Show quoted text On Thu, Aug 22, 2019 at 5:47 PM sailor24u@...

Carl Damm All Messages By This Member #9507 I recently had this conversation with an experienced surveyor. He has been using a shaft brush on his own boats. Of coarse this requires a hull zinc and bonding system that many Tartans lack. He regularly meters out the conductivity of shaft zincs and finds the majority of the time they do not maintain a good conection to the shaft. Or prop.
