Idle RPM for Merc 30 4-stroke

[GotFish]

I recently purchased a used 2003 Merc 30 4-stroke. It is the carberated motor, not the fuel injected version. The motor is "clunking" into gear a bit harder than I would like, and I suspect the it is idling too high. I don't yet have a shop manual for this motor.... does anyone have the spec for the motor speed at idle? Thanks for any info!

Hi GotFish,<br /> from my Mercury service manual for<br /> 30/40 fourstroke carbureted engines,<br /> Nov 2001. <br /> Specifications for idle speed are for<br /> a warm engine, in the water.<br /> <br /> Idle RPM (out of gear) 900 +/- 25 rpm<br /> Idle RPM (in forward gear) 800 +/- 25 rpm<br /> <br /> slightly older than your engine, but I<br /> am sure it still applies.<br /> Good luck,<br /> Don
