Jim, I have Wareagle 754 VS stick steer with 55 hooked to two batteries and works fine for every application except pulling cranks. It will get the speed but run time is about 4 hrs. I pull with my big motor most of the time and steer with Terrova. If I was not going to use big motor I would definitely go with the 80 plenty of power and much longer run time especially on your boat.
