Ultraflex shift cable

Three points are important: (1) Function (throttle or gearshift), (2) Length (based on existing cable length/marking or accurately measured including routing path), and (3) End fittings/connection standard at the control box and engine/drive. The quickest way is to read the stamping/part number from the old cable or send a photo of the end fittings—then the correct Ultraflex model can be clearly identified.

Ultraflex offers cables in various connection standards and adapter solutions that are compatible in practice with common control boxes and motor connections. However, a blanket statement that “it always fits” would be misleading—the cable series, connector, and the existing hardware on the control box/motor are decisive. Therefore, always check the stamping, the connector (thread/clip/articulation), and any existing adapters. If you specify the old system, we can narrow down the suitable variant.

For motors/drives, the motor-side linkage is crucial: type of end fitting, mounting point, stroke/shift travel, and any specific connection kits. Many setups use common standards, but the model year, control/shift box, and modifications can still play a role. The safest approach: replace the old cable 1:1 (imprint/part number) or compare end fittings or Ultraflex adapters.

Common causes include too-tight bending radii, kinked or chafing cable routing, corroded end fittings, missing counter-brackets, or incorrect adjustment of the shift box. A “too-long” loop in the cable can also increase friction. Ensure a clean, tension-free route, protect cable entries against chafing, and check end fittings and pivot points for play and corrosion.

Safety and function: Secure cables against chafing, avoid kinks, maintain minimum bend radii, properly secure end fittings, and firmly mount counterholders. Then adjust and test the neutral position and shift travel: Engine off (gear in/out), then test run at the dock. If you are unsure or encounter safety-related issues, we recommend having the system inspected by a specialist workshop.

Most modern shift cables are designed to be low-maintenance. Lubricant applied in the wrong place can attract dirt and cause damage over time. It is particularly important to perform regular visual inspections (casing, kinks, end pieces) and check for smooth operation. If shifting is jerky, replacement is often the most reliable solution—especially if the casing is damaged or water may have penetrated it.
