Re: hours
remember, hours on an OB motor are good, until you get up to commercial ranges.
In addition to maintenance (which is more important than hours) it's good to know how those hours were spent. A lot of slow trolling is not good--but also not a reason not to buy it.
Also if the motor isn't propped correctly, the hours can be deceiving. A mechanic told me that every minute you run at 1000 rpm higher than the recommended max, you add an hour to the engine's age. So when you test drive, see what the top end does, or ask your seller if you can, what's top speed and rpm's.
On an newer motor like this one, hours can be a helpful piece of information; on an old motor, it's meaningless except in the extreme ranges. Also, hour meters can be worse than odometers for reliability, excpet perhaps the built-in ones on the computer.
I added an hour meter when I bought my used boat so it says 150 hours for a 2003. But I put those hours on it in the last 14.5 months, with very little use for 3 of those months.
