I just realized that I hadn't given an update on the new motor. The 90hp Yamaha 4 stroke with the Yamaha 15" pitch prop does really well. Engine height was perfect(thanks McGillicuddy). It has the same top speed as the 115 Johnson and gets right up on plane. I did remove the second battery and relocated the battery up to the console for a little better weight distribution. I've only had 3 people in the boat and I suppose I'd see a bigger performance difference when loaded down, but so far I'm really impressed with the little 90.
