Confirming what others have said. We've had our QSM11 powered 48 for almost eight seasons and have it dialed in correctly.
2000 RPM - 39 GPH total - 67% load - 21 knots

Wow, you are getting 4mph more than I am at the same fuel burn. Being a 2011 I do weight a little more in the stern with the extended cockpit and hydraulic lift with 800lb dingy hanging farther out in the back but that’s a lot more speed for the same fuel burn. Impressive.
