This spark plug wrench for outboard motors is a manual special tool for removing and installing spark plugs. The angled design makes it easier to guide the working end of the wrench under the engine cover, where space around the spark plug can be limited.
The wrench is double-ended and designed as a tubular/box-type hex wrench with an approximately 90° angled head. The angled end has a documented wrench size of 21 mm and is intended for spark plugs with a 21 mm hex. The wrench size of the opposite end is not definitively documented.
The tool is made of hardened steel and has a shiny, silver-colored metal surface. The universal design refers to the tool's general use for outboard motors, but specific compatibility depends on the spark plug hex and the access conditions under the engine cover.
The spark plug wrench is also included as a component in the folding tool kit with item no. 47.357.10.
