As Rick said, 60 or 62 is the way to go with an Aquasport. Also, the Edge is a freshwater motor - you need to go with the Riptide if you are going to put it in salt water.
If you can afford it, consider one of the models with a wireless remote, or, even better, the iPilot. Being able to control the motor from anywhere on the boat is a great feature.
See ya on the water!
