I'm starting to look for a new aluminium boat 16' to 18'. What's everyones opinion G3, PolarKraft, Fisher, or Lowe? I want between a 50 to 90 HP motor. What's pros & cons of 2 stroke vrs 4 stroke and which make Mercury, Evinrude, Yamaha? I mainly crappie fish in the fall, winter & spring and bluegill fish in the summer. Oh yeah I forgot I want one with a guaruntee to catch fish.
