Low rpm on evinrude e-tech 90hp

I have a Bayliner 1700 capri.It's length is 5m.I recently bought an evinrude e-tech 90hp but the rpm is way to slow that I was expecting.With 2 people on the boat the engine's rpm goes up to 5000 and with 4 people and some luggages on the boat,the engine's rpm is only 4700.I am worrying if the propeller is the problem.The engine's propeller brand is  solas 13,5 x 15.Can anyone tell me if the propeller is the problem?Should I put a 4 blade propeller in the engine?If yes what nummber should I choose?Or should I go on a smaller size and stay in the 3 blade propeller?

 

In addition,can anyone tell me the max rpm of evinrude e-tech 90hp?
