So I finally pulled the trigger on a boat to get out and start fishing on the lake. I usually move around Eagle Mountain Lake in a kayak, but I recently bought an inflatable boat from http://www.saturnboats.com/. I payed for the 16' Saturn Inflatable Boat, and I want to know what motor would work best for it.

I want to catch a few fish, troll around a little, but I don't want to waste too much gas. Any input on what motor would be best for my little, tiny ship?
