Explore America's Campgrounds

Adjusting the idle on an Evinrude outboard motor helps to increase the motor's efficiency. This is particularly important if you use your motor as a trolling motor in addition to a main source of propulsion. Just like any of the other small maintenance chores, you can adjust the idle yourself with a minimum of fuss and tools.

Items you will need

  • 3/8-inch open-end wrench

  • Standard slotted screwdriver

Loosen the idle speed screw's lock nut with a 3/8-inch open-end wrench.

Turn the idle speed screw with a standard slotted screwdriver until the tachometer indicates the idle speed is between 800 and 900 RPM.

Tighten the idle speed screw lock nut.
