Overview

The Somusen 0583740/583740 Dual Plug Wire Ignition Coil is a direct‑fit replacement designed to work with a broad range of outboard engines. Crafted for Johnson, Evinrude, and OMC models, it covers a wide horsepower spectrum from 40HP up to 175HP and supports 2-, 4-, and 6‑cylinder configurations. Built to endure marine conditions, this coil aims to deliver reliable ignition consistency across seasons of use.

Key Benefits

  • Wide compatibility: engineered to pair with 40HP–175HP engines across multiple cylinder layouts.
  • Dual plug design: aimed at improving ignition reliability and consistent performance during starts and under load.
  • OEM-quality materials: constructed from durable components and subjected to strict testing prior to shipment.
  • Durability and performance: designed for long-term use in demanding marine environments.

It’s sized to fit a range of 2-, 4-, and 6-cylinder engines, making it a versatile choice for many outboard configurations.

  • Maintenance-friendly: replace worn coils to sustain engine responsiveness.
  • Potential performance: paired with proper wiring, it can contribute to steady spark delivery during acceleration.
