Trident Marine 10' Black Stern Flex Hose w/Transom Flange

The Trident Marine 10' Black Stern Flex Hose with Transom Flange (Model TFK-10) is a purpose-built marine conduit system designed to safely route wiring, control cables, and hoses between the transom and outboard engine on boats. This black hose assembly (Trident Marine 129 series) connects to the Trident flange part #142-2000, providing a sealed, organized pathway for critical engine control systems that must withstand repeated flexing and saltwater exposure.

Built with extraordinary flexibility and wire-reinforced construction, this stern flex hose resists crushing, abrasion, and UV degradation—critical properties in the marine environment where UV rays accelerate hose deterioration and engine vibration creates constant mechanical stress. The hose also delivers good chemical resistance, protecting against fuel, coolant, and saltwater spray. The 10-foot length accommodates most outboard configurations, allowing adequate routing distance without excessive slack or tension on control runs. The transom flange mounting system ensures a secure, watertight connection point where the hose exits the transom.

This assembly is essential for weekend anglers, offshore fishermen, and serious boaters who need reliable engine integration. Whether you're maintaining an existing outboard system or upgrading worn stern flex hose, this Trident Marine product provides the durability and flexibility demanded by saltwater and freshwater marine conditions. Proper conduit protection extends throttle and trim responsiveness while preventing water intrusion into electrical connections—directly impacting engine reliability and safety at sea.

Trident Marine stern flex hose systems are industry standards for original equipment and aftermarket outboard replacement. Verify compatibility with your specific transom flange (part #142-2000) and engine configuration before purchase to ensure proper fit and function.
