I have a single d4-300if engine with 484 hours on it. The engine 4 years old. Took the boat out today and the engine will not exceed 1900rpm at WOT. Turbo pressure is 0 and I cannot hear the turbo running at all. The engine runs fine otherwise, starts right up, no smoke, idle is stable. Temperature is at 185F, oil pressure is at 61 max. I did see a few drops of oil coming from the bottom of the heat exchanger, but oil level did not change since the oil change last fall.
The engine went through full maintenance then: oil and fuel filters, impeller and a coolant flush.
Any suggestions will be greatly appreciated.
