Okay. That is a pretty standard pump for the 6.3544.
If you take a look at that last line, it shows pump settings. The last one is the "Wide Open Throttle (WOT) -- *NO* load" setting: 3190.
In other words, if you'd leave the boat in neutral, let it fully warm up, and push the throttle lever on the pump full-open, that is the RPM that you'd expect to develop. Test at home at your own risk
In terms of a general algorithm, the WOT-load RPM is about 10% below this. Rough numbers, 2871 RPM. So, this is fully consistent with my memory that the publsihed nominal full-load WOT RPM is 2800 for your engine.
Remember that this number is a nominal number for a nominal boat in a nominal configuration, etc, etc, etc. It wouldn't be unusualy to see a boat in the real world clock in at 100 or 200 RPMs below this, even if folks weren't intentionally trying to make the engines run slower to get less noise and vibration.
Also, in order to ensure that the throttle controls don't get slammed ofrward and over-rotate the throttle lever on the pump, most installers set the controls so that they cannot actually move forward far enough to get the engines to full throttle. I've had a few installers tell me they try to set it back by about 100rpm. I guess that is a common heuristic for "usually enough rotational margin to make sure that, as things age a paniced driver can't slam it forward and break things."
