I was told I had to increase the size of my tabs to resolve a issue, but truth be told I needed to have wait a few seconds longer or change the pitch of my prop. I left the previous set unpainted due to the possibility dissimilar metal corrosion and they corroded away even with the zinc installed. So I painted this set and had zero issues with corrosion. Most important thing is that they are in great shape. You can remove the paint easily with a scrapper, if you so choose. The other small part of the hing plate that attaches to the boat, is not included. It remained with the boat and was used with the new two foot tabs.
