Idle Adjust Mercruiser 3.0L

[RSHOOTER]

I have a 2007 Glastron GT-205 with the 4 Cyl. Mercrusier.
This year the idle seems low in neutral about 500 rpm. The engine runs fine but it can once in a while stumble when it's put in gear due to the low RPM.
I don't want to mess with the mixture screws. Can I add maybe 200 RPM by adjusting the cable? Which direction?
Thanks.

Don't ever mess with the mixture screws. Don't adjust the cables unless you know what your doing.There is an idle set screw you can adjust.Use a tach/dwell instead of the on the boat the one you have in the boat might be off. Jerry

Thanks Jerry. I think the mixture screws require a special tool.
Where is the idle adjust screw?
