I recently purchased a 2000 NT37 with a Cummins 5.9BTA 330hp motor. The motor and Northern lights Genset have about 4300 hours. The manual lists maintenance schedules out to 2 years, never once mentioning injectors. The manual has instructions for replacing them but no recommendation as to when. With this being a single screw, I am trying to get motor up to date on all maintenance. Should injectors be on my to-do list, or not something to be concerned about.
The motor smokes a bit when cold, but runs good. It is still very efficient, pushing the boat at 8knt and burning about 2gpm. I don't think I have any indication of injector issues.
Thoughts? Other parts I should be concerned about? Water pump?
Things in process:
5.9BTA: Coolant flush, new thermostat, new belt, new air intake, new transmission oil, engine oil and filters, fuel filters, impeller, wet exhaust inspection (read the articles), heat exchanger maintenance, aftercooler maintenance.
Genset: Coolant flush, thermostat, belt, air filter, oil filter, fuel filters, new brushes, impeller.
Injectors? Something I should add to the list?
