Looking at a 2002, what to look for??

[Flux]

Going to look at a 2002 V-Drive. I have read the buying an older boat article and it's helpful. Any suggestions on what to look for when buying aside from the obvious condition of the boat stuff??

Should the prop still spin freely on a V-Drive??
How about the best places to look for oil drips ??

Anything about 2002 yr models that was bad or will go bad.

Boat has about 90 hrs on it.

Thanks in advance.
