Just bought a 21' Ranger Reata with a 200HP e-tech HO on it. Run great but hear is the question. We are about 3500' in elevation and the boat runs about 47 MPH wide open at ~~5400 RPM. Will this speed increase once the motor is broke in?? If so, ~~ what is the break in time on this motor?

The optimum rpm for that motor is in the 5500-5700 range for all around performance. Due to the thinner air at your elevation, your motor will not put out the same hp as it will at sea level. Temperature makes a difference also.
Your local dealer should be familiar with performance and setup for your rig in your location. You can play with engine heights and different props to get the rpms up a bit and into the recommended range.
There is no break in on the motor that you have to worry about. It will add extra oil above 2000 rpm for the first 2 hours and you can run the motor the way you want.
