This is a replacement regulator rectifier for Kawasaki jet skis, made by WSM to replace OEM part number 21066-3718. It fits the STX-12F, STX-15F and the Ultra 250X through Ultra 310 series PWC. The regulator rectifier controls charging voltage from the stator to the battery, so it is a common part to replace when a ski has charging or battery problems and the rest of the charging system tests good.
