I have had my boat since Memorial day.

it has a 2006 Evinrude ETEC 90 hp which had been running at 4900-5000 RPM.

Today I had the boat out and it ran at about 4700 RPM.

It sounded fine, but cannot explain the loss of RPM. Only difference is I had the Bimini top up. Water was pumping fine, no indicators of any sort.

I did not see anything on Prop, but did not pull prop.
