I figured as much. You've got the rake of the sheer interrupted with 2 X 8 butt blocks with 3/4 ply butting together, figures there would be a knuckle. Not too worried about it and found a Evinrude 28 so I am sure it will scoot right along with no appreciable impact.
Sanded the entire boat today and filled a couple of holes, dings and miscellaneous voids to clean it up a bit. Rolled/brushed on another coat of primer and am pretty pleased with how it's looking. Grain is mostly gone and pretty uniform texture. I am much more of a woodworker than I am a finisher so I am keeping my fingers crossed.
Hoping to roll the black bottom paint on for Father's Day!
