Kinda new to boating, purchased a used 18' Bass Buggy Pontoon with a 1996 Evinrude 50 SPL. Getting ready to purchase a new 06 50 HP E Tec and was wondering if I should just go ahead and buy a 60 hp instead. Is the differences worth it? Will there really be much of a diffence? I would appreciate any and all opinions. Thanks for you time.
