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

The Trident Marine 10' White Stern Flex Hose with Transom Flange is the backbone of any outboard engine installation, routing critical wiring, control cables, and cooling hoses from your transom to the engine itself. Serious anglers and boaters know that a reliable stern hose assembly prevents water intrusion, maintains clean cable runs, and keeps your engine compartment organized—factors that directly impact engine longevity and performance. This 10-foot length accommodates most single and multi-engine configurations, making it an essential replacement part for anyone running outboard power.

Built to Trident Marine's 129W specification, this white flex hose features a flexible design that accommodates engine tilt and trim without crimping or pinching internal wires and cables. The integrated transom flange (compatible with Trident flange part #142W-2000) provides a secure, watertight seal at the transom face, preventing saltwater spray and moisture from entering the cable cavity. The wire-reinforced construction maintains structural integrity under marine vibration and pressure changes, while the white finish resists UV degradation and blends with modern helm aesthetics. At 4.2 lbs, it's lightweight enough for easy installation yet durable enough to handle years of offshore duty.

Whether you're rebuilding an older rig or upgrading to new outboards, this stern flex hose is essential for twin and triple engine setups where clean cable management prevents throttle lag and improves control response. Retrofit and OEM installers specify this hose for its seamless integration with standard transom flange systems. For optimal results, pair with Trident's matching flange hardware and ensure all cables are routed without sharp bends during installation—proper routing extends hose life and maintains system reliability in saltwater, brackish, and freshwater environments.
