Thank you all for your thoughts.

In response, the flybridge and pilothouse tachometers match. The mechanic verified that both were correct with a timing light.

Air filters and turbo were checked. Both determined to be fine.

Timing ratios were also checked as well as the governor.

Another thought came to mind which I thought I'd pass along. Under no load, the RPM steadily increases with the increase in throttle. Under load, the RPM reaches 2000 with 10-15% of the throttle still remaining. The final 10-15% of the throttle movement has no effect on the RPM's.
