Prop for 16'7" 115hp

I'm wondering if anyone has any experience running a 115 hp motor on a 16/7 whaler. I have a 1963 hull in sound shape. I realize it is rated for 100 hp max, but given the circumstances, the 1977 Evinrude 115 hp is all I have to work with until I can save up for a more appropriate engine. This engine does not currently have a prop and the tach wiring does not seem to work so I have no prop and rpm info to start with. I am not looking for a speed boat, I just want a prop that won't over rev. Anyone have any diameter and pitch reccommendations or any tricks on how to read RPM without a typical OMC tachometer?

T.B., I ran an Evinrude 115 on my Montauk for nearly 20 years.
I feel the boat was a little over-powered, but only at high speeds. The hole shot was quick but controllable. Hence, I have re-powered with a 90 hp.
My 115 came with a 19in pitch prop which was fine for general use. However, my 6'3" 200+lb
You can get a product called a "Tiny-Tach" which easily attaches to your engine and will act as an hour meter as well as tachometer. Part # TT226NR-2C. Usually around $35-40 and available on the 'net.

Joe, thanks for the info. I'll look around for the tach.
