Hi guys I need help I have a Ranger R27 with the Yanmarn 180 hp engine ..Just serviced the engine replacing oil filter both diesel filters air filter and although the boat starts right away and the engine runs smooth I experience a alarm that begins to beep when I was over 3000 rpm and the engine lose power ..I have to turn of the ignition switch and restart the engine and the engine will turn right away and run smooth until I hit again the 3000 rpm.....Know has even gone worse the alarm will beep at 2400 rpm..I check the turbo and it funcioning well also check if I had any vacuum hose lose and haven't found nothing wrong .When I go to the engine monitor I don't have any code stating a problem.I notice the load on the monitor seems to be high at low rpm but really not sure if that's how it should be...Will sure appreciate any help with this issue..Thanks and happy sailing.
