Perfect fit

I own a late model Bayliner , parts are hard to get sometimes. The anodes on my trim tabs were really in bad shape. They were a perfect match and fit

Q: null This is a pair correct?
9 years ago7 Answers
A: I would describe the round zinc anodes as 2 halves. They can act as a sandwich when bolted to a metal trim tab, one half on the top and the other half on the bottom. Both would be exposed to the water. If they are used on a surface that is exposed only on one side to water, then you would only need to use one half of this zinc and bolt it to the water side, with the spare half stored and available for the next season.

Q: null Do these zincs include mounting screws?
11 years ago4 Answers
A: No mounting screws. The zinc's require a mounting hole to be drilled in the trim tab to receive the zinc. the screw that attached the two sections is also the mounting screw to hold the zinc in place.
