So I arc marked from the corners as best I could (not much room between the instep and jackplate) and then measured to the base of each bottom jackplate corner. My measurements were the same as far as I could tell for each side. Please let me know if I did that correctly, as it seemed more of a horizontal measurement than vertical.
Does that mean the whole transom is off? It is not level in regards to the instep below the jackplate which is how I noticed it in the first place. Just trying to get a better understanding of how this happens. Thanks!
