So here it is with template cut down
I measured from center of pad 2” I think? Then I measured beam to beam and then chine to chine all lined up very close to my center line of pad. Within a 1/8-1/4” or less. One of those other marks hit my line exactly…
Again this is the X dimension of 14 5/16” +2” so 16 5/16” on the center hole or x dimension.
Here’s the dry fit of the transom assembly. Need to let stuff dry and cure and rains rolling in. I want to glass around the cutout and the holes to prevent water intrusion. Will report back when can.
