OK, your 1,000 RPM down from max, meaning that your either over propped, or way down on HP.
You can live with being over propped, just use your brain and don't over strain her. Maybe cruise
at 2000 RPM and not much more.
I would start by having it warmed up, and put it at an idle speed where it's smooth, the lowest smooth speed. Then one at a time loosen the injector nut til fuel starts spurting out and listen for engine speed to drop and it should start to shake, tighten nut, go to next injector.
If you find one that doesn't get rough and drop RPM, you have a problem cylinder. They should all be the same
Do check your water temp at the exhaust, but check it after its been under a load, let it get a chance to get hot if its going to.
