Yamaha Motor Co., Ltd. 63M-85570-20-00 Ignition Coil

Yamaha 63M-85570-20-00 Ignition Coil is a marine engine ignition component that converts low-voltage input to the high-voltage spark required for combustion in Yamaha two-stroke engines. It is used in Yamaha WaveRunner models including Wave Raider 1100, Wave Venture 1100, and Exciter 220 (1995–1998), where reliable spark generation supports proper engine starting and steady performance. The coil is designed for mounting in the engine electrical/ignition assembly and features an encapsulated construction with insulated wiring leads to withstand the harsh marine environment. It provides a high-voltage output to spark plugs to ensure proper firing under marine operating conditions, contributing to consistent ignition timing and engine reliability. This is a genuine Yamaha replacement or equivalent aftermarket part intended for marine ignition systems. Common replacements include Yamaha 63M-85570-00-00, 65E-85570-00-00, and 63V-85570-00-00.
