Sierra Marine supplies OEM-grade ignition replacement parts that keep your engine starting and running strong. This collection covers ignition coils, modules, pickup sensors, contact sets and related parts.
Ignition components must match your specific engine make, model and year. Sierra cross-references many OEM part numbers, so the surest path is to find your original part number or your engine application and match it to the Sierra listing. A wrong fit will not perform and can leave you stranded.
Ignition coils convert battery voltage into the spark that fires the plug. Modules and pickup sensors control timing and trigger the coil. Contact sets and condensers serve older points-style ignitions. When a motor runs rough, misfires or will not start, these parts are common culprits. Confirm the Sierra part number against your engine application before ordering to be sure of a correct fit.
Match by your engine make, model and year, or by the original OEM part number. Sierra cross-references many OEM numbers, so confirming the application is the safest way to get a correct fit.
An ignition coil steps up battery voltage into the high voltage needed to create a spark at the plug. A weak or failed coil causes misfires, rough running or a no-start condition.
Sierra makes replacement parts designed to meet or match original equipment specifications and cross-references many OEM part numbers. Always verify the listed application matches your engine.
