I am going to be buying a boat for the Kenai and limited saltwater use and I am considering various brands of motors including Yamaha, Suzuki, and Honda - all 4 strokes. I have also thought about a Tohatsu 50 but that is just available in a 2 stroke. My perception is that while the 2 stroke is lighter it is louder. My understanding is that the Suzuki has a 6 year warranty but the others are 2-3 years. So, what is your experience with these motors.
