Wide transoms and long rigging runs can make things tight, and this harness keeps you from forcing sharp bends or stretching cables. It lets the wiring take a smoother path so everything feels calmer at the helm. It’s a simple add-on that makes big multi-engine layouts easier to rig and maintain.\u003c\/p\u003e\n\u003chr data-start=\"536\" data-end=\"539\"\u003e\n\u003cp data-start=\"541\" data-end=\"1061\"\u003e\u003cstrong data-start=\"541\" data-end=\"557\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"557\" data-end=\"560\"\u003e    • \u003cstrong data-start=\"586\" data-end=\"607\"\u003e20-Foot Extension\u003c\/strong\u003e – Adds plenty of length for wide beams and long routing paths.\u003cbr data-start=\"670\" data-end=\"673\"\u003e    • \u003cstrong data-start=\"699\" data-end=\"719\"\u003eOuter-Engine Use\u003c\/strong\u003e – Designed for the outer engines on triple or quad setups.\u003cbr data-start=\"778\" data-end=\"781\"\u003e    • \u003cstrong data-start=\"807\" data-end=\"825\"\u003eOEM Connectors\u003c\/strong\u003e – Factory plugs that lock in firmly.\u003cbr data-start=\"862\" data-end=\"865\"\u003e    • \u003cstrong data-start=\"891\" data-end=\"911\"\u003eFlexible Routing\u003c\/strong\u003e – Helps avoid pinched spots or tight corners.\u003cbr data-start=\"957\" data-end=\"960\"\u003e    • \u003cstrong data-start=\"986\" data-end=\"1008\"\u003eSteady Signal Path\u003c\/strong\u003e – Keeps throttle and shift communication consistent.\u003c\/p\u003e\n\u003chr data-start=\"1063\" data-end=\"1066\"\u003e\n\u003cp data-start=\"1068\" data-end=\"1236\"\u003e\u003cstrong data-start=\"1068\" data-end=\"1099\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1099\" data-end=\"1102\"\u003e    • Triple engine\u003cbr data-start=\"1141\" data-end=\"1144\"\u003e    • Quad engine\u003cbr data-start=\"1181\" data-end=\"1184\"\u003e    • Outer-engine helm pathways\u003c\/p\u003e\n\u003chr data-start=\"1238\" data-end=\"1241\"\u003e\n\u003cp data-start=\"1243\" data-end=\"1650\"\u003e\u003cstrong data-start=\"1243\" data-end=\"1279\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1279\" data-end=\"1282\"\u003eThe extra length lets the wiring follow a natural route instead of being squeezed through tight areas. Controls tend to feel smoother because nothing is kinked or pulled too hard. It also gives you more room to work when you’re back there doing service—big boats get cramped fast, and this helps keep things open. Everything feels a bit more organized and predictable.\u003c\/p\u003e\n\u003chr data-start=\"1652\" data-end=\"1655\"\u003e\n\u003cp data-start=\"1657\" data-end=\"1898\"\u003e\u003cstrong data-start=\"1657\" data-end=\"1672\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1672\" data-end=\"1675\"\u003eOEM harnesses hold up well to heat, vibration, and saltwater spray.
