I also took the time to fit the cowl. The engine prop shaft exits dead center of the front opening. It was a bugger to get this cowl to fit properly. The problem I ran into was that the top of the cowl is flat, while the top of the deck is curved. I had to transition is as best I could with out restructuring the whole deck. As much as I try not to use any filler, I did have to use a very small amount to get the transition right.
