I bought a 2004 2120 dvsc this year, the Yamaha 150 4 stroke had 221 hours on it and was well maintained. The reason for the low hours was it had a 9.9 kicker and after getting to the fishing grounds on the 150 it was all day on the 9.9 - To me this seems like the best of both worlds. Low hours (with good reason) and always professionally serviced with all the paper work in place. I on the other hand love the 150 and use it all the time; 282 hours and counting. I have always looked at it like a car, once you hit that 100,000 mile mark things are going to start wearing out and needing replacement, just from basic wear and tear on internal parts. With a boat motor I would feel the same way. As we start heading toward 1000 hours my mind wonders toward repower issues. I have no idea if it’s right or wrong, I’m a rookie and don’t know what to expect. But to me common sense says low hours and less use equals a healthier motor, as long as the motor received its routine maintenance by a qualified Yamaha professional. Just my two cents, but I don’t know if I’m right or wrong yet. I’m guessing based on my experience with the cars I’ve owned.
