The Honda 98079-5787G Spark Plug (ZFR7F) is a genuine OEM spark plug designed for BF115 and BF130 outboard motors. As a direct Honda OEM part, it is manufactured to the same specification as the plug installed at the factory, ensuring the correct heat range and electrode geometry for these outboard applications. Confirm your outboard's serial number against the fitment table before ordering, as Honda supersedes spark plugs at serial breaks within a model line.
Key Features
- OEM Heat Range and Electrode Specification — the ZFR7F designation identifies a specific heat range and electrode configuration matched to the combustion characteristics of the BF115 and BF130 outboards, not a generic substitute.
- Direct OEM Replacement — supplied by Honda as the genuine replacement plug under part number 98079-5787G, fitting directly into the cylinder head without modification.
- Outboard-Specific Fitment — listed for BF115 and BF130 outboard motors; verify your serial number against the compatibility table to confirm the correct plug for your serial range.
- Ignition Consistency — a correctly specified plug produces a clean, consistent spark across the operating RPM range; a worn or incorrect plug causes misfires, rough idling, and increased fuel consumption on the water.
A spark plug ignites the compressed air-fuel mixture inside each cylinder, initiating the combustion stroke that drives the engine. In an outboard motor, where operating conditions include sustained high-RPM cruise, saltwater air exposure, and frequent throttle changes, the plug must maintain a stable spark under varying load. When a spark plug wears — through electrode erosion or fouling — ignition becomes inconsistent, leading to rough running, hard starting, and a noticeable drop in power and fuel efficiency. Replacing it with the correct OEM plug restores clean ignition and protects the engine from the secondary damage that prolonged misfires can cause.
