The general condition of the motor should indicate low or high hours as well. A merc dealer can connect to the ecu and tell you more. It may be worth it. The engine is fine.

What should I expect from a Mercury compression test?
Bearing in mind there are a lot of things that can affect compression testing, not the least of which is highly inaccurate pressure gauges, test being run without the throttle open, dry cyl, carbon build up…..those numbers look low. I would expect a 3 litre 250 hp in good condition to read about 20 pounds higher.
