Another thing about your newer 4 strokes. In the last couple of years Mercury and Yamaha have redesigned their motors to be competitive with the 2 strokes. They have reduced the weight, increased the torque and HP where they perform right beside a comparable 2 stroke of any brand. From everything I can read if you buy a Suzuki you don't have much need for a service center. They just don't have warranty failures and I'm sure honda would fall right in there also. I have a 04 Yamaha and it's had one set of plugs and the oil changed.
