Hi
Saw this post. The Drag n' Fly is a cool boat. However, I suggest that you step up the power for that hull. For more excitement, try putting a 7.5 or similar engine to make it go. With a tuned pipe the engine will run nicely and make the boat run as intended. I think that you will be disappointed with the performance of the .40 marine sport in this hull. In either case, Macs Products is the place to go for exhaust systems.
Years ago, my brother ran a Supertiger .35 airplane engine with Cool Clamp in his Drag n' Fly .19 size boat - ran pretty good. The point is that the Dumas wood hulls need more power than recommended to make them fun.
Have Fun!
