Compatible Engines

The SIERRA 18-5108 impulse coil is a critical component of the ignition system, responsible for generating the trigger signal that initiates sparking at the precise moment in the engine cycle. Without this component, proper engine operation is impossible, and its failure results in a lack of ignition, leaving the boat stranded. Due to the nature of aftermarket parts production, compatibility must be verified by the manufacturer's catalog number 18-5108 or the original OE (Original Equipment) number. We do not provide a list of specific engine brands here to avoid selection errors. If you have any doubts about fitting this part to your unit, contact our store support – we are happy to help verify compatibility based on the serial number or model.

Installation and Operation

Replacing the impulse coil is a task that requires precision and caution. Before starting work, be sure to disconnect the battery cables to prevent accidental short circuits or electric shock. During disassembly, pay attention to the condition of the wire insulation and clean the mounting area of any contaminants that could interfere with the sensor's operation. When installing the new SIERRA coil, ensure it is properly secured and the wires are connected according to the engine's electrical diagram. Regular inspection of this component helps prevent unexpected breakdowns during a cruise, ensuring safety and confidence while steering the boat.
