I cleaned up Bulkhead D in preparation of setting the HS mount. I extended my waterline to BH D and cut two sections of wood 7 3/16 to mark location up from the waterline. I started to get it up 7 3/17 on the sides and set level. I got it close but I have a couple of more iterations before perfect. My dog Ace also was checking out his location in our plane. He can't wait to go flying!
