I have a 2001 Outback LS with 320 EFI Indmar. What rpm setting will equate to 25 mph so I can calibrate by speedometers?

My dealer told me 3000 rpms == 30 mph

I have a Kamberra with 320 EFI Indmar 4 blade prop... GPS show 20 mph at 2000 rpms and this held true up to 35 mph and 3500 rpms Don't think the difference in the weight of the boats will make that much of difference...
