Default Sterba Prop Info

My 0-320 E2A 160 hp came with a Sterba 68x72 prop.

There really wasn't any information in the prop logbook.

Just curious about a few things.
1. What is the safe max continuous RPM?
2. I have not put wheel pants or fairing on yet, but I am see a speed of 130 kts at 2350 rpm while at 2500 feet. Seems a bit low. Would this be more of a climb prop? Or is this about normal?
3. What RPM should I see with a 160 hp?

Thank you,

Email: ed_sterba@excite.com ("ed_sterba" - the underscore doesn't show up with the hyperlink in some fonts.)

He usually responds within a day.

Perfectly normal. Reconvene after installation of gear leg fairings and wheel pants. Significant speed and rpm increases are typical.
