Hermco Bracket Measurements for 1974 Tsunami

[Copper Collar]

As far as I know it is the original. The "bow" looked even and seemed to be right in the middle.


I'm having the entire transom re done (from the inside w/ coosa) to fill in the I/O holes and to add more layers inside since it is going from I/O to a bracket.


Edit:

I went back out and used the straight edge across the transom at 4 different heights, starting at the outdrives and moving up. I then went diagonal from the port top of the transom to the starboard trim tab and then from the starboard top to the port trim tab. Good news is that the 1/2" I said before is more like a 1/4" at most. There are actually two dips that match the twin outdrives, that get worse the closer you move to the gimbal where they are around a 1/4".
