Adjusting the idle screw on your Mercury outboard can indeed help with idle performance. The idle screw is responsible for controlling the engine's idle speed. Turning it clockwise generally increases the idle speed, while turning it counterclockwise decreases it. To address a rough idle or stalling issue, you might want to start by turning the idle screw slightly counterclockwise to reduce the idle speed. Make small adjustments, and test the engine's performance each time. Additionally, it's a good idea to ensure that your fuel system is clean, including the fuel filter, and that the spark plugs are in good condition. Always refer to your engine's manual for specific instructions related to your model, and if you're unsure or uncomfortable making adjustments, it's advisable to consult with a professional mechanic or your local Mercury dealer. Adjusting the idle screw can be a simple fix, but it's important to do it with care to avoid causing other issues. Just sayin...
