On most Evinrude side-mount “pilot” control boxes, the front knob (the small round one facing forward, usually near the base of the handle) is the friction or throttle tension adjustment.
Its purpose:
It doesn’t change engine power or trim directly — it just controls how freely the throttle lever moves.
If your control also has a pull-out feature on the main handle for neutral warm-up, that’s a separate function — the front knob is still just the friction/tension adjuster.
