It's on page 58 in my Perkins engine manual. Says "Adjust idle speed to 625 Rev/min". . . . . . "but idle speed may vary based on application."
I have mine set at 600 rpm's, (because we're often fishing and a little lower idle speed is better for that purpose.) But I usually idle the throttles up to 800 rpm's for docking. Makes the boat control response a little quicker and it's still within the shift RPM spec's for the BW Velvet Drive Trans.
