Planning a 16-Inch APEX Helm Installation: Dimensions & Clearance
Planning a 16-Inch APEX Helm Installation
Master helm space measurement, sight line preservation, cable strain relief, and mounting selection before installing your 16-inch marine display.
Installing a massive 15.6-inch full HD screen like the Humminbird APEX 16 Chartplotter brings unmatched clarity to your dashboard. However, executing a flawless APEX 16 helm installation requires precise planning regarding physical dimensions, cable routing depth, and surrounding helm control ergonomics.
1. Key Humminbird APEX 16 Dimensions to Consider
Before cutting into your glass console or mounting heavy-duty brackets, verify these critical physical dimensions:
📐 Physical Dimension Breakdown:
- Unit Width: ~17.6 inches (447 mm)
- Unit Height: ~10.4 inches (264 mm)
- Unit Depth (Screen to Back): ~3.3 inches (84 mm)
- Depth with Rear Cables Attached: Allow at least 6.0 to 6.5 inches of clearance behind the console.
2. In-Dash Flush Mount vs. Gimbal Bracket Mount
In-Dash Flush Mounting
Provides a sleek, factory-custom look. Requires precise cutout using Humminbird's exact template. Ensure you have rear access behind the console to secure mounting studs and route dual Ethernet, power, and transducer cables.
Gimbal Bracket Mounting
Allows screen tilting to eliminate glare in direct sunlight. Great for flat dash consoles or heavy offshore setups. Requires sturdy backing plates to support the weight during rough seas.
3. Essential Helm Space & Clearance Guidelines
- Steering Wheel & Throttle Clearance: Turn your wheel to maximum lock in both directions and push the throttle into full forward gear to ensure your hands won't strike the display glass.
- Sight Lines & Compass Interference: Mount the screen below your primary line of sight when driving over plane. Keep the unit at least 12–18 inches away from magnetic steering compasses to prevent heading deviation.
- Cable Bend Radii: Never bend thick heavy-duty power and transducer cables at sharp 90-degree angles immediately exiting the back panel. Maintain a minimum 3-inch bend radius to prevent internal wire breakage.
