With the old transom out, you should be able to use a large piece of cardboard or some 1/4" ply to mock up a template. Lay it up against the outside of the transom and line it up with the rivets for the transom pocket. Trace out the side angles of the hull and take a little off to accommodate the inside placement. Keep trimming and test fitting as needed until it drops into place, then trace out the top of the transom curve/cap. Use the template to transfer the cut lines to your doubled up 3/4" transom wood. You may need to account for the angle/bevel at the top of the transom "wings". Test fit before sealing and use the holes in the hull to mark out where you need to drill, paying attention to whether the transom holes need to be drilled at a 90 or angled. I believe most are on the 90, but never done an '87 or newer before.

Don't know for what motor but if it's a Merc

Doesn't look like a BIA bolt pattern to me

I think he's asking for a template for the actual transom itself, not the bolt pattern for the outboard mounting.

Yup, I have had to do that before.
Cardboard to get it close, then play with the wood to get it right.
Since most of us use two 3/4in pieces of plywood, the first one is the main template, the second one is a copy.

bolt holes, I had good luck by drilling halfway through using the outside skin as a template. then drill from the inside to try and link the two holes up.

Not perfect, but I filled any void created with epoxy.
