My Universal inboard diesel has recently weakened for unknown reasons. At full throttle it reaches 2000 rpm but the boat is barely moving. It used to max out at 3000 rpm. I'm new at engine repair. Any recommendations?

Will the engine reach full RPM in neutral? When was the last time you removed and inspected your exhaust riser? (Those can get plugged up over time.) What is the condition of your prop? Just a few items for starters....

Yes. When in neutral it reaches full RPM. When in gear it is significantly weaker. The boat also barely moves forward at full throttle.
As another poster suggested, the prop may not be functioning very well.
...Either fouled badly or eaten up by stray currents. Perhaps. (Does your marina have a reputation as an electrically "hot" marina?)
Can you have a look at in in the water? Either by direct observation or putting a waterproof camera down there on a stick?
