Adjusting RPM

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?

I can't say how to adjust the idle , but I would check the tach readings against the engines to ensure they are correct before making changes.

When the throttles are pulled down to their idle stops in gear does the boat go in a straight line or pull one way ? Slow speed handling is much easier when you don't have to fool with the sticks to get the same prop speed from both sides.

Hopefully someone with this model can chime in.
