Sierra 18-5297 Electronic Ignition Conversion Kit for 4-Cylinder GM Marine Engines

The Sierra 18-5297 Electronic Ignition Conversion Kit upgrades traditional points-and-condenser ignition systems to modern solid-state electronic ignition on 4-cylinder GM marine engines. This drop-in conversion module fits Delco 4-cylinder distributors with screw-down caps and is commonly used on MerCruiser and OMC stern drive applications.

Key Features:

• Replaces points and condensers for true solid-state ignition
• Easy one-piece installation with simple 2-wire hookup
• Uses your existing standard coil, distributor cap, and rotor
• Accurate to within 1/4 degree timing accuracy across 0 to 6000 RPM range
• 3 ohm resistance for reliable performance
• Compatible with Sierra Flame Thrower performance coils (18-5466 and 18-5469)

Cross References: Interchanges with GLM 72510 and Mallory 9-26900. Note: Not compatible with shift assist modules.

This conversion kit delivers improved starting, smoother idle, better fuel economy, and reduced maintenance by eliminating the need for periodic point adjustments. Designed specifically for marine environments and engineered to meet or exceed OEM specifications.
