Teleflex Control Boxes & Parts: Precision Command on the Water

When it comes to putting a skipper firmly in command of throttle and shift, few names carry the weight of Teleflex. For decades, Teleflex Marine — now operating under the SeaStar Solutions umbrella — has been the benchmark for marine engine control systems, trusted by recreational boaters and commercial vessel operators alike. Their control boxes and parts represent the culmination of that engineering legacy, offering a lineup that spans single-lever top-mount controls, twin-engine dual-lever boxes, and a comprehensive range of replacement hardware.

Dual-Function Single-Lever Design

One of Teleflex's most enduring contributions to boating is the popularization of the dual-function, single-lever control box. These units operate both shift and throttle through a single lever — using two cables internally — making close-quarters maneuvering and docking far more intuitive. Teleflex dual-function single-lever controls are also available for twin-engine applications, where each lever manages both shift and throttle for a separate engine independently. As Teleflex's own documentation notes, single lever control has become the most popular control style used today largely because of how dramatically it simplifies boat handling.

Key Product Lines & Features

Teleflex offers a broad spectrum of control box styles to suit virtually any vessel configuration:

• Top-Mount Controls (CH Series): Models like the CH2100, CH2800, and CH5300 cover everything from ski boats to twin-engine yachts. The CH5300 (formerly the MT3 Twin) has been an industry standard for twin-engine installations for years, featuring a neutral safety switch and independent throttle warm-up capability.
• Side-Mount Controls (MV-3 Series): The heavy-duty MV-3 combines throttle and gear control in a single lever with specialized versions for outboards, sterndrives, inboards, and even ski and jet boats.
• Single-Function Controls: For applications where separate shift and throttle levers are preferred, single-function controls give operators dedicated, tactile feedback for each input.
• Electronic Control Systems: Teleflex's KE-series electronic controls — including the KE-4a and KE-5 — are designed for full electronic engine/gearbox combinations, supporting up to five helm stations, easy station transfer, and a built-in self-diagnosis system.

Broad Compatibility & Replacement Parts

A major reason Teleflex control boxes remain a go-to choice for repower and refit projects is their exceptional cable and engine compatibility. Many Teleflex control boxes accept standard 3300/33C universal cables as well as OEM-style cables from Mercury/Mariner, OMC, Johnson, Evinrude/BRP, Volvo, Yamaha, and others — making them a practical drop-in solution without requiring a full system overhaul. Beyond the control head itself, Teleflex offers a full ecosystem of replacement parts: ball joints, cable clamps, screw pivots, conversion kits, neutral safety switches, and knobs. This modular, service-friendly design means worn components can be replaced individually rather than swapping out the entire unit.

Built for the Marine Environment

Every Teleflex control box is engineered with the marine environment in mind. Corrosion-resistant materials, permanently lubricated gear mechanisms, and robust housing construction ensure reliable performance whether the vessel operates in freshwater lakes or demanding saltwater conditions. Features like the neutral safety switch, neutral warm-up pull-out, and adjustable throttle brakes add layers of operational safety and convenience that experienced boaters have come to rely on.

Whether you're restoring a classic single-engine runabout or upgrading a twin-engine sportfishing boat, Teleflex control boxes and parts deliver the smooth, precise feel that has defined marine throttle-and-shift systems for generations.
