Mercury Marine Side Mount Control Boxes

Mercury Marine Side Mount Control Boxes are a proven choice for boats that need dependable throttle and shift control in a compact, console-friendly design. Mounted on the side of the helm or console, these controls keep your layout clean and comfortable while delivering the familiar lever feel boaters trust for docking, cruising, and everyday operation.


Why Choose a Side Mount Control Box

  • Space-saving side mount design that works well on smaller consoles
  • Comfortable lever positioning for precise throttle and shift control
  • Reliable cable-based operation that is easy to service and maintain
  • Great for upgrades when replacing older controls or refreshing a helm layout

What These Controls Do

Side mount controls serve as the command center for throttle and shift. Depending on the model and rigging configuration, they may include or support:

  • Throttle control for smooth, predictable power delivery
  • Shift control for positive forward, neutral, and reverse engagement
  • Neutral safety function on compatible setups
  • Trim and accessory functions when equipped

Rigging Tips for a Smooth Feel

Control performance is heavily influenced by cable condition and routing. If your lever feels stiff or shifting is not smooth, the issue is often in the cables—not just the control box. A refresh can make the helm feel dramatically better.

  • Replace worn cables to reduce friction and improve response
  • Avoid tight bends in routing that increase lever resistance
  • Use OEM-fit components for correct connections and long-term reliability

When to Replace a Side Mount Control Box

  • Sticky throttle movement or increasing lever resistance
  • Notchy shifting or difficulty finding neutral
  • Corrosion from salt air or moisture exposure
  • Console upgrades that require a different control style or layout
