My mount is rusted out down inside the hull. Never seen this type of set up before and like I said its so rusted out that I can't get a clear read on how it all fits together. At the top there is a 6" by 3" inch plate with six mounting holes, and a shaft that runs down to the bottom of the hull where it meets a flat metal plate that is completely rusted out. It also has 2 large nut that appears to be for tension adjustmen ??? I'm looking for anyone you can clear this up for me and hopefully steer me in the direction to get replacement parts
