The factory Idle setting plate on the motor says 650 RPM. The sticker on the AirBox says that idle should be no higher than 800RPM or could cause shifting problems. Thats all fine and good. What I'd like to know is how/where to set the idle (lower). Is it simply turning a screw (in/out) like engines in the "old" days ? If so, where can I find the idle adj screw ?

Did a forum search for 'MERC IDLE set' but nothing turned up. :confused:

Had the boat out yesterday..It "Clunks" (shifts HARD) going into reverse..Its IDLING at 1100 RPM but (see above) it SHOULD idle at 650 RPM..How do I turn the idle DOWN..Is there an IDLE ADJUSTMENT SCREW ?

So in two years you still have not figured this out??? And yes -- you are correct that this is not rocket science. The picture is of a 75 HP Merc but a 40/50/60 is similar. If you look just below the fuel filter you will see a label. That label says IDLE SPEED with and arrow pointing to the screw.
