Engineered Marine Products Edge Control Cables. For Mercury, Mariner and Mercruiser engines. Unique design of conduit provides structural integrity and a tighter minimum bend radius. Provides greater efficiency due to low-friction materials and construction. Built with the optimum gap between inner core and conduit, resulting in significantly less backlash. Wiper seals are made from polyurethane and impregnated with lifetime lubricant to minimize friction and extend service life. Minimum bend radius: 4 inches. Travel: 3.82" (97mm). Conduit: 0.28" (7mm). Inner: 0.07" (1.9mm, stainless steel solid wire).
