It will also sum up that 1100 hours into 1000 RPM buckets for you, so you can see if it spent most of its life running wide open, idling, or crusing. The military/police guys on the boating forum I'm on report 3K hours plus on their well-maintained Yamaha fours.

It really depends on a few factors - engines that aren't propped right will not go as many hours as well as engines that aren't on a routine maintenance schedule. Regardless of brand, today's modern outboards will give excellent service - IMO at least 6,000 hours. Commercial guys get around 8 to 10 K hours as mentioned above.

I have been told that 450 hrs on a four stoke is nothing. I do know guys that have a couple thousand hrs on there and the motors are still pretty strong. I believe i have about that many hrs on my motors and they are 08 model. If this rest of the boat is in good shape then i would expect that the motors are the same.

The use of the engine and the location. For boats that live in Florida and get used regularly, we would say that the average number of hours for a boat will be around 2,000 hours.
