E-J,

Do you know what prop you are running. Maybe a lower pitch/ larger diameter prop would help with the porpoising. It looks Luke your motot is mounted in the center holes, so maybe another hole up might help with the top end. Others with more prop tuning skills might chime in on this, but swapping out my Old aluminum Merc prop for the much larger diameter stainless Stiletto made a world of difference.

Just a thought.....

BTW, I'm interested in how this turns ou since the 60 Merc Big Foot is on my short list as possible repower for my 15 Dauntless.
