What top RPM for 1969 OMC 120 hp?

[BlackSmoke]

Just out of curiosity, what top rpm should I expect from my '69 OMC 120 hp 4-cyl. electric shift stern drive? It's in a 17' tri-hull fiberglass bowrider. Sorry, don't know prop pitch. I've been topping out around 4,500. Should I expect more?

Your right on the money especially for a motor from 1969.<br /><br />Bob
