Replacement Gimbal Mount Kit 740149-1 for Hummingbird Helix 8/9/10

In this review the Replacement Gimbal Mount Kit 740149-1 is evaluated for anglers and boaters who need a durable, adjustable mount for Hummingbird Helix units. The bottom line: this kit is for anyone who wants a simple, corrosion-resistant gimbal bracket that secures the control head, reduces screen shake with ratchet teeth, and is straightforward to fit in most installations. It delivers function first, making the display easier to read in rough water without adding unnecessary complexity.

Key Features

• Compatibility: Fits all Helix 10, Helix 9, and Helix 8 models so buyers can use one bracket across multiple generations of displays.
• Secure hold: Ratchet teeth provide a positive grip that reduces screen shake and helps keep the control head at the chosen viewing angle.
• Corrosion resistance: Black coated metal construction resists rust for longer life in demanding marine environments.
• Complete kit: Includes bracket, two rubber washers, two gimbal knobs, and four screws and washers so there are no extra parts to source.
• Clear instructions: Comes with installation steps that guide users through drilling, sealing, and fastening for a reliable mount.

Who It's For

The kit is aimed at recreational and professional boaters who use Hummingbird Helix chartplotters and want a dependable, adjustable mounting solution. It is especially useful for people replacing a worn gimbal or upgrading an older mount to something with better anti-shake hold.

Those who should look elsewhere include users who need a flush or recessed mount rather than a gimbal style, or people seeking a tilt-and-swivel system with powered rotation; this kit is a manual gimbal bracket focused on secure positioning rather than motorized movement.

Pros & Cons

Pros

• Solid, coated metal construction offers good rust and corrosion resistance for marine use.
• Includes all necessary mounting hardware and gimbal knobs for a straightforward install.
• Ratchet teeth reduce screen vibration and help maintain a clear view while underway.

Cons

• Manual gimbal adjustment only, so it lacks powered or multi-axis swivel features that some users might want.
• Installation requires drilling and sealant, which may be undesirable for those seeking a no-drill solution.
