Yanmar 50hp lifespan?

Hi
I am looking at buying a boat which has a 50hp yanmar that is approximately 25 years old. Assuming this has been relatively well looked after and only casual leisure usage, how long might I expect this engine too last.
It starts a runs perfectly and has now visual signs of age, however, I don't want to buy it and things start to fall apart. Can I expect at least another 10 years use out of it?
Cheers
 
If the install is sound and the gear and prop properly selected and the maintenance done, you should be able to get several thousand operating hours out of the engine. Infrequent use usually results in shorter times between overhauls. when in doubt (or paying a large sum of money) it is always prudent to hire an accredited surveyor to inspect the entire boat.
