Yamaha Wire, Lead 4 - 6E5-82147-00-00. Built like a tiny lightning rod, this 10-inch (253 mm hole-to-hole) bonding lead quietly protects your Yamaha's mid-section and lower unit from stray-current corrosion. A flat, tinned-copper braid carries faults and static charge straight back to the block, while the tough black PVC jacket shrugs off engine-bay heat, salt spray, and the occasional wrench slip. Pre-crimped ring lugs-one 6 mm, one 8 mm-drop onto factory studs without trimming or soldering, so the swap takes all of five minutes.. Why keep one in the spares drawer?. Maintains a solid ground path between powerhead, mid-case, and lower unit for F300/F350 and classic 115-225 hp two-strokes. Tinned-copper braid resists oxidation far longer than bare-copper knock-offs. Molded strain-reliefs at each lug prevent work-hardening from vibration. Supersedes older 6U0- and 6T4-series leads-direct fit, no adapters. 253 mm length neatly follows the original harness route; no chafe, no slack loops.
