A guy at boaters world told me the other day that the 2005 and 2006 tohatsu 4 strokes are awesome motors, he says they weigh 82 pounds which is very light for a 4 stroke, and they are very effecient and reliable. I currently have a 1971 mercury 9.8 and it is getting to be less and less reliable. Does anyone know how many years of service one could expect from a tohatsu, or how they pan out compared to the big names?
