Dear people, I introduce myself. My name is Darío, I'm from Argentina, Buenos Aires and a sailing enthusiast. I have an Aquamare 690 cruise ship from 1985 in good condition. But for some time the engine (Volvo Penta AQAD30A 110 HP with turbo) does not give more than 2500 rpm and at 2000 rpm it emits black smoke. I already checked injectors, changed the diesel filters, replaced hoses and even changed the fuel tank. I also had the turbo repaired. It only remains for me to have the injector pump checked and repaired.
Some tell me that I may be "exceeded propeller", that is, the propellers are large. However, the DP290 manual advises propellers from A3 to A10. I have placed an A6 game, that is, I am in the middle range, but the problem remains.
I will be grateful if you can help me to specify the diagnosis through your experience.
Thanks for your help. Cordially.
