420666142 Ignition Coil for Sea-Doo RXT STD 230 1503 2018-2019

Ignition Coil for Sea-Doo RXT STD 230 1503

This ignition coil is a replacement electrical component that supplies the high-voltage spark required to ignite the air-fuel mixture on Sea-Doo RXT STD 230 1503 watercraft, cross-referenced to OEM part number 420666142.

Overview

This ignition coil keeps the ignition system of Sea-Doo RXT STD 230 1503 personal watercraft firing with the strong, consistent spark the 1503 engine needs. It steps up low-voltage current into the high-voltage pulse that jumps the spark plug gap for reliable combustion at idle and under load. A practical replacement for riders and technicians dealing with a weak or failed coil.

Specs At A Glance

Good To Know

Q: What causes an ignition coil to fail on a personal watercraft? A: Heat, vibration, and moisture exposure over time can break down the coil's internal windings or insulation. Once resistance drifts out of spec, spark strength drops and misfires follow.

Q: Should I replace more than one coil at a time? A: If the coils share similar run hours and one has failed, replacing the set can prevent repeat downtime. Inspect the spark plugs and boots at the same time for a complete ignition refresh.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
