Mercury Marine spark plug boot and terminal kit in black is a genuine OEM kit for repairing or assembling spark plug wires and other high-tension leads on compatible marine engines. The kit consists of an angled, black protective boot and a separate, locking metal terminal with a double crimp.
The heat-resistant construction protects the connection at the spark plug and is designed to prevent spark loss. The product is supplied as a single kit and features Mercury Marine part number 85-63709A1 as well as GTIN/UPC 745061166189.
The kit is used on select Mercury and Mariner outboards from 4 to 225 hp, Mercury 200/225 DFI, 225/250 EFI 3.0L and 300 ProMax, as well as select MerCruiser engines, including 4.3L, 5.0L, 5.7L, 350 MAG MPI, 6.2L MAG MPI MIE, 7.4L/454 Magnum, 357 Mag and 383 Mag. It is also documented for select Mercury Sport Jet engines and older Force, Chrysler and Sears outboard motors. Compatibility varies by engine configuration, so the engine model, serial number and existing part number should be verified before ordering.
