Adjusting RPM
Posted: May 12th, 2022, 7:22 pm
I have a 2003 Carver 444 with Volvo TAMD 63P A engines. The engine have 1400 hours on them the best I am able to come up with since the previous owner kept poor records. The Stbd engine starts and idles at 683 while the Port engine starts and idles at 585. I was told the only way to adjust the idle was electronically, but this boat has the KE-4 system and I can clearly see the idle adjustment bolt on both engines. Is this something I need to be concerned about and adjust the idle rpms or is this common on this boat?
