420266070 Ignition Coil for Sea-Doo 3D RFI 800 2005

Ignition Coil for Sea-Doo

This ignition coil for Sea-Doo provides the high-voltage spark needed to fire the plugs on 3D RFI 800 models, cross-referenced to OEM part 420266070.

Overview

This ignition coil for Sea-Doo is an electrical component that steps up battery voltage into the high-voltage pulse that fires the spark plugs. It restores reliable spark on 3D RFI 800 models from 2005, helping the engine start cleanly and run smoothly. It is intended for riders replacing a failed or weak coil on their personal watercraft.

Good To Know

Q: What causes an ignition coil to fail on a PWC? A: Heat, vibration, and moisture exposure over time can break down the coil windings or insulation, leading to weak or intermittent spark. Replacing the coil restores proper ignition voltage.

Q: Will this coil fit my exact model? A: It is built as a direct-fit replacement for the OEM coil on the listed model and part number. Verify your machine year and part number match before ordering.

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