It comes with two drive keys included and replaces BRP OEM parts 396725, 389557, 437080, and 432954, covering a solid range of OMC 3-cylinder water pump applications.\u003c\/p\u003e\n\u003cp\u003eImpeller dimensions are as follows:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInner Diameter (ID): 19.15 mm\u003c\/li\u003e\n\u003cli\u003eOuter Diameter (OD): 91.5 mm\u003c\/li\u003e\n\u003cli\u003eWidth (W): 25.4 mm\u003c\/li\u003e\n\u003cli\u003eBlades: 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe hub is compatible with key 47-02357 or 47-01757, and two keys are included with this impeller so you have what you need to complete the installation without a separate parts order.
