Check out Tohatsu 4 strokes. They make motors under 30 hp for Mercury, Evinrude and Nissan. I bought a brand new 8 hp for my boat last year. It was very reasonable. I had it shipped and saved over $1000 compared to other brands. Take the cover off and it is exactly the same as the other motors. My big motor is an Etec 150 and I love it but my kicker uses way less gas when trolling.
