Uflex B501B/L Single Lever Top Mount Control | Black with Neutral Lock

The Uflex B501B/L is a rugged and reliable single-lever mechanical control designed for single-engine boat configurations. This model features a modern, low-profile Black Finish and an integrated Neutral Lock safety trigger. As the "No Trim" version, it provides a clean, ergonomic handle design for boats that do not require integrated trim control, such as inboards or vessels with dash-mounted trim switches.

Clean Design and Reliable Performance

The B501 series is engineered for precision and durability.¹ By removing the trim switch from the handle, Uflex offers a more streamlined grip that reduces the chance of accidental trim adjustments and simplifies the internal wiring. This makes it an excellent choice for workboats, classic restorations, and high-performance boats where the driver prefers tactile separation between throttle and trim functions.

Key Features:

• Single Engine / Dual Action: A single lever manages both shifting and throttle. The first part of the stroke engages the gear, and the remainder of the travel increases engine RPM.

• Neutral Safety Lock: Includes a manual trigger on the handle that must be depressed to move the lever out of neutral. This prevents accidental gear engagement by passengers or gear.

• Neutral Warm-Up Mode: The lever can be pulled out laterally to advance the throttle for engine warm-up without engaging the propeller.

• Heavy-Duty Construction: Built with a die-cast aluminum housing and a UV-resistant black powder coat, ensuring it stands up to intense sun and saltwater spray.

• Adjustable Friction: An accessible external screw allows you to fine-tune the lever tension to prevent "throttle creep" or to lighten the movement for easier shifting.

• Safety Switch Included: Comes with the X12 neutral safety switch, ensuring the engine will only start when the lever is in the neutral position.

Technical Specifications:

• Performance Boats: Best for drivers who use foot-throttle trim or separate dash switches for more precise hull leveling.

Installation Note:

The B501B/L is a direct replacement for many industry-standard top-mount controls. For the most responsive and "friction-free" experience, it is highly recommended to install this unit with Uflex MACHZero cables, especially if the cable run involves multiple bends.
