I may be seatrialing a boat with a couple of 3cyl diesel straight inboards installed.
These are inter. rated at 3600 rpm/ continuous rated near 3500. The owner claims both do 3000 at WOT, but no excess smoke.
Can someone check my plan?
1) make sure props and hull are clean
2) insure full travel of throttle cables are achieved. I think I should be able to see the travel stop on the engines.
3) With warm engines, do a high idle test, likely with a handheld tach.
4) If high idle does not achieve 3600, then adjust it.
5) Now what to do if high idle IS achieved without adjustment? Compression test?
6) If compression is good, reduce prop pitch?
anything missing?
