Yep , in my first post I stated that judging by the paint , it was a mid eighties Evinrude ,which according to your link is max at 7,000 RPM.
Well , the tach is a tiny tach knock off set at one pulse per revolution.
the GPS is a 7yr. old TomTom.
The boat is a 1448 (or 42 can't remember) Fisher purchased at Walmart in 1997. Don't know the gage of the aluminum hull ,but its not the heaviest.
The prop is a new Solars 9.25 X10 ( ran once on the other 15hp rude)
The numbers I posted were indeed the ones I saw on the tach and the GPS.
The motor was trimmed out to the 2nd hole, boat was riding flat on top of the water. Very little wake and only a little spray off the sides.
The boat is still loaded as it was when it was in the water, I'll post pics of it , the motor and prop in the morning.
