Yamaha 80 - How many hours?

I am not sure about the 2000, but many newer motors can have the hours read on the diagnostic computer. A mechanic who has the equiptment should be able to tell.

But--it depends on the condition of the motor as much as the hours. If it is a 4 stroke, they can go much longer than a 2 stroke if properly cared for. Do a compression check and visual. Even a compression check may not tell the full story. As I recollect there was one where the engine had not been run for some time, and the compession was low, but with running it came back up. Stuck rings?

There is a good chance that the 80 could out last your ownership of the boat...for example upgrade size of boat in a few years.
 
Harry,

You could talk to the owner and get him to discuss how and how often he used the boat. For many users, 100 hours per year would be a lot. If the owner went out 4 hours per day for two days every weekend, that would be 400 hours. But, for many users, 100 hours per year would be a lot. Slow cruising is less stressful than full throttle pulling water skiers.

Also ask about when and where he had the maintenance done.

Unfortunately, just asking does not guarantee honest replys, but it may give you some indication. You can also get clues as to condition by the general maintenance of the boat and trailer.
 
In addition to being available on the computer read out to the mechanic at the shop, my 2005 Yamaha 90 EFI shows total hours in the middle of the tach/instrument gauge in digital form. The 2000 model had carburetors, and may not have that feature, however.

That one has no ECM connection to read hours . A leakdown and compression test is the way to go . And good maintenance records will tell you alot . As Bob said those things can go multi thousands of hours and run like new .
