898103T58 – Igniter Coil – Mercury/Mariner

The 898103T58 igniter coil provides strong ignition power for select Mercury and Mariner outboard engines. It generates the spark energy your engine needs to start reliably and run smoothly. You install this coil in the ignition system of compatible 2.5 hp and 3.5 hp four-stroke outboards. It works with stock wiring and mounting points, so you avoid complicated modifications.

This part suits engines that use conventional ignition systems with a separate coil. When your original coil weakens or fails, you may notice hard starting, rough idle, or stalling under load. Installing this genuine Mercury-spec coil restores spark intensity and improves combustion consistency. With better spark strength, you get more complete fuel burn and stable performance across the RPM range.

Technicians and boat owners use this coil when tuning or servicing ignition systems. It fits directly into factory ignition assemblies and pairs well with OEM plugs and wiring. Because it resists heat and vibration, it holds up to marine conditions where other coils might fail prematurely.

Using a quality ignition coil like this helps reduce misfires and promotes smoother throttle response. It also helps protect other ignition components by ensuring the timing system operates correctly.
