RPM's and top speed
I have a 2019 Rinker 290 EX with a Volvo Penta 380 HP Motor. The hull has been bottom painted. The manual from Volvo Penta says i should be able to get the RPM's up to between 5600 and 6000 if not there is something wrong. I have never been able to get the RPM's over 5100 with a top speed of 40.9 MPH. Should i be concerned?
