The NGK DPR6EA-9 is a standard spark plug, stock number 5531, with a resistance of 5000 ohms. It has a nickel ground electrode core and a copper center electrode core. The plating resists corrosion to ease fitting and removal. It is listed for 1995-2002 Mariner, 1995-2006 Mercury and 1995-2005 Yamaha outboards, along with some ATVs and motorcycles. Check your engine manual for the plug your maker recommends.
Our take
The 5000 ohm resistance and copper core are the specifics here, and the outboard list runs 1995 to 2006 for Mercury. Plenty of motorcycles share this plug, so confirm your engine's recommended plug in its manual.
