  • Direct OEM Replacement: This trigger assembly is a direct fit for Mercury/Mariner OEM part number 98450A10. It also replaces aftermarket part numbers 339-5501​ and 339-5502. It is the complete timer base assembly that controls ignition timing for reliable engine performance.
  • Solves Ignition Timing Issues: Effectively fixes common problems caused by a failing trigger, including no spark, engine misfires, rough idle, hard starting, and loss of power. A critical component for proper engine operation across all RPM ranges.
  • Wide 2-Cylinder Compatibility: Fits a broad range of Mercury and Mariner 2-cylinder outboards​ from 6HP to 25HP. This includes popular models like 6, 8, 9.9, 10 (XR10, Sea Pro, Marathon, Viking), 15, 20, and 25 (Super 15) HP.
  • Critical Serial Number Fitment: This part is for 2-cylinder (2-cyl.) engines only. Compatibility is determined by engine serial number​ (e.g., 0G760300, 0P017000, 0P325500, 0T980000, 1B000001). Always verify your engine's serial number falls within the provided ranges before purchasing.
  • Complete Assembly for Easy Installation: Comes as a complete unit. While designed for direct replacement, installation requires setting the correct air gap. We recommend consulting a service manual for proper installation and timing procedures.
