compression numbers

[Dire Straits]

Hi guys
Looking for some advice on acceptable compression numbers on a 1997 S250 OX66 Saltwater Series II with 652 hrs that I'm looking to buy. All cylinders are 100 psi.. The engine is not on the boat so I can't run it but the engine looks well care for. Any advice would be help full.

Thanks
Dave

Those motors have a 115-120 psi compression when in new condition.Need to test at WOT,warmed up and have kill switch pulled.My opinion 100 psi would be fine.
