Replacement Start Stop Ignition Button for Sea-Doo 580cc-951cc PWC
Direct replacement for Sea-Doo OEM 278000427 and 278000501. This handlebar start/stop button is the ignition switch used to crank and kill the engine. The switch contacts corrode from saltwater exposure and age, causing intermittent starting or complete failure. Common symptoms include no-crank, engine not shutting off, or needing multiple presses. This replacement restores proper ignition function. Fits 1995-2000 Sea-Doo 580cc-951cc 2-stroke PWC including GTS, GTI, GTX, GSX, XP, SP, SPI, SPX, and HX models. OEM-spec connector for direct fit.
