The Honda 98069-5771P Spark Plug (DR7EA) is a genuine OEM ignition component designed for Honda BF25, BF30, BF35, BF40, BF45, BF50, BF75, and BF90 outboard motors. As a direct OEM replacement, this spark plug is specified to Honda's own standards for heat range and electrode geometry, ensuring the ignition system performs exactly as designed. Confirm fitment against your outboard's serial number using the compatibility table below before ordering, as Honda supersedes parts at specific serial breaks.
Key Features
- OEM Heat Range and Electrode Spec — the DR7EA designation identifies the exact heat range and electrode configuration Honda specifies for these outboards, so combustion timing and ignitability are maintained across all operating conditions
- Drop-In Replacement — supplied to Honda's OEM specification, this spark plug installs directly in place of the original without modification or rejet
- Broad Outboard Coverage — listed for Honda BF25, BF30, BF35, BF40, BF45, BF50, BF75, and BF90 outboard motors; confirm your serial number against the fitment table, as Honda issues supersessions at specific serial breaks
- Ignition Reliability on the Water — a worn or fouled spark plug causes hard starting, rough idling, and misfires under load; replacing it with the correct OEM plug restores clean ignition and consistent power delivery
A spark plug is the component that ignites the air-fuel mixture inside the engine's combustion chamber. At each firing stroke, high-voltage current from the ignition coil jumps the electrode gap, producing a spark that drives combustion and turns the crankshaft. In a marine environment, spark plugs are subject to heat cycling, salt air exposure, and the sustained loads of open-water operation, all of which accelerate electrode wear and deposit buildup. A degraded plug leads to misfires, difficult starting, increased fuel consumption, and loss of top-end power — replacing it with the correct OEM part, part number 98069-5771P, restores full ignition performance and keeps the outboard running at its rated output.
