A.A Ignition Coil for Mercury MerCruiser Volvo Penta – Direct-Fit Replacement (898253T24) Durable Marine Spark

The A.A Ignition Coil is a direct-fit replacement coil engineered to restore reliable spark for Mercury, MerCruiser, Volvo Penta and OMC engines that use part numbers like 392-806529A1, 898253T24, and equivalents.

When marine ignition performance falters, swapping in a high-quality coil that matches OEM fit and function is one of the fastest ways to get an outboard or sterndrive back to smooth operation. This A.A coil is manufactured to meet or exceed original equipment specifications and is cross-referenced to several common Mercury and Volvo Penta part numbers, so it fits a wide range of small- to mid-size marine engines without modification.

Which engines and part numbers does this coil replace?

This coil is designed as a replacement for multiple Mercury, MerCruiser, Volvo Penta and OMC applications. It covers several factory part numbers often cited in service manuals and parts lists, allowing straightforward swaps during routine tune-ups or repairs.

• Replacement for Mercury part numbers: 392-806529A1, 898253T24, 32193A2
• Also cross-references: 38547, 835998, 915735, 18-5433
• Fits many common outboard and stern drive ignition systems used in recreational boats
• Designed for direct-fit installation with factory mounting points and terminals

How does this coil improve starting and running reliability?

A properly functioning coil delivers the consistent high-voltage spark necessary for ignition; a worn or failing coil can cause hard starts, misfires, or rough idling. This A.A coil is built to provide stable secondary voltage and insulation that resists moisture and vibration common in marine environments.

• Stable spark output reduces misfires and hesitation under load
• High-quality insulation protects against moisture and salt air intrusion
• Robust construction resists vibration and thermal cycling
• Maintains correct spark timing when paired with OEM components

What should I expect during installation and fitment?

Installation is straightforward for anyone familiar with basic marine engine service. The coil is manufactured as a direct replacement, so it uses the same mounting points and electrical connections as the original unit. Follow safety procedures: disconnect the battery and mark wiring before removal.

• Direct-replacement design uses factory mounting holes and terminals
• No modification required for compatible engines and wiring harnesses
• Simple bolt-on replacement; basic hand tools typically suffice
• Recommended to inspect spark plug boots and wiring during installation

What durability and compatibility features does this coil offer?

Marine engines operate in challenging environments, so components need to resist corrosion, heat and moisture. This A.A coil is engineered with those conditions in mind and undergoes quality checks to meet or exceed OEM expectations for performance and longevity.

• Meets or exceeds OEM electrical and mechanical specifications
• Materials chosen for corrosion resistance in marine atmospheres
• Manufactured to tolerate repeated heat and vibration cycles
• Quality-tested to ensure consistent output and reliable sealing

Who is this for: The A.A Ignition Coil is intended for boat owners, marine mechanics and service shops needing a dependable, OEM-compatible coil for Mercury, MerCruiser, Volvo Penta and OMC engines. It’s a practical choice for routine maintenance, mid-season replacements, or when diagnosing ignition faults—especially where an exact fit and proven performance are priorities.
