When the standard harness won’t reach cleanly—or the routing path winds around bulkheads—this extension keeps you from pulling the wiring tight or forcing awkward bends. It lets the harness run in a smoother, more natural line so everything feels calmer at the controls. On larger offshore rigs, that extra length makes the whole setup far easier to rig and service.\u003c\/p\u003e\n\u003chr data-start=\"604\" data-end=\"607\"\u003e\n\u003cp data-start=\"609\" data-end=\"1157\"\u003e\u003cstrong data-start=\"609\" data-end=\"625\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"625\" data-end=\"628\"\u003e    • \u003cstrong data-start=\"654\" data-end=\"675\"\u003e35-Foot Extension\u003c\/strong\u003e – Long reach for wide transoms and extended routing paths.\u003cbr data-start=\"734\" data-end=\"737\"\u003e    • \u003cstrong data-start=\"763\" data-end=\"783\"\u003eOuter-Engine Use\u003c\/strong\u003e – For the outside engines on triple and quad DTS setups.\u003cbr data-start=\"840\" data-end=\"843\"\u003e    • \u003cstrong data-start=\"869\" data-end=\"887\"\u003eOEM Connectors\u003c\/strong\u003e – Factory ends that snap in solid and stay locked.\u003cbr data-start=\"938\" data-end=\"941\"\u003e    • \u003cstrong data-start=\"967\" data-end=\"987\"\u003eFlexible Routing\u003c\/strong\u003e – Helps avoid tight corners, pinched runs, and stressed wiring.\u003cbr data-start=\"1051\" data-end=\"1054\"\u003e    • \u003cstrong data-start=\"1080\" data-end=\"1105\"\u003eReliable Control Path\u003c\/strong\u003e – Supports steady throttle and shift communication.\u003c\/p\u003e\n\u003chr data-start=\"1159\" data-end=\"1162\"\u003e\n\u003cp data-start=\"1164\" data-end=\"1332\"\u003e\u003cstrong data-start=\"1164\" data-end=\"1195\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1195\" data-end=\"1198\"\u003e    • Triple engine\u003cbr data-start=\"1237\" data-end=\"1240\"\u003e    • Quad engine\u003cbr data-start=\"1277\" data-end=\"1280\"\u003e    • Outer-engine helm pathways\u003c\/p\u003e\n\u003chr data-start=\"1334\" data-end=\"1337\"\u003e\n\u003cp data-start=\"1339\" data-end=\"1778\"\u003e\u003cstrong data-start=\"1339\" data-end=\"1375\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1375\" data-end=\"1378\"\u003eWith this much extra length, the wiring can follow an easy, natural route instead of being squeezed into tight spaces. Controls usually feel smoother because the harness isn’t kinked or stretched across the boat. It also opens up the rigging bay, giving you room to work during service instead of fighting a cramped layout. For bigger offshore boats, it simply makes everything feel better organized.\u003c\/p\u003e\n\u003chr data-start=\"1780\" data-end=\"1783\"\u003e\n\u003cp data-start=\"1785\" data-end=\"2059\"\u003e\u003cstrong data-start=\"1785\" data-end=\"1800\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1800\" data-end=\"1803\"\u003eOEM harnesses stand up to vibration, heat, and saltwater better than generic cable.
