A few transom questions

The boat is a 72’ V20 with a 150hp Evinrude. I am wondering whether the transom is bad or not. How much should the transom flex when pushing up and down on the lower unit. 1/16 or 1/8 or less? When I push on areas of the transom there are not any soft spots that depress in.

If it is bad… I am debating whether to go the traditional way or Arjay 6011 method. Is the Arjay any less structurally sound than the traditional? Disadvantage…. Advantages…?

If I were to use the traditional method let me make sure I have this right….

• Lift the top cap off to obtain access to the entire top of the transom.
• Remove the old wood.
• Cut two 3/4" marine grade plywood pieces to shape and epoxy the together (What kind of epoxy should I use?).
• Lower into the empty cavity.
• Shim to maintain 1/4" gaps on both side of the wood and a consistent transom thickness.
• Fill the gaps with epoxy resin. (Again, what kind is recommended?)
• Put the cap back on and put it all back together.
