I am trying to find out witch of these 2 outboards is A better motor? the 70 hp is A 2011. the 90 is A 2008. I have asked around a lot and just about everyone says by far yamaha is the best outboard. being there used I wonder if there are issues with them? is the 70hp A better motor? or the 90hp? is yamaha the very best out there? my boat is rated 90hp max. I feel that 70hp would be enough. 14'x6'6'' is this A mistake? I am very new to this type of activity and dont want to fall into A money pit. ....................so hopefully someone knows something, thank you very much.
