Rather than replacing an entire propeller when the hub wears out, spins, or cracks, this hub kit lets you rebuild the propeller's hub assembly so the prop keeps performing like new. The kit uses corrosion resistant brass splines paired with a nylon hub body, a combination chosen to stand up to constant saltwater and freshwater exposure while still absorbing vibration and chatter transmitted from the propeller to the gear case and engine. Because the hub is a separate rebuildable component, this system eliminates the common failure points of spun hubs and hub cracking that otherwise force a full propeller replacement.\u003c\/p\u003e\u003cp\u003eThis is the 503 hub kit, and it is designed for OMC Cobra 400 stern drives with 2.3 to 3.0L engines (1978-89). The kit ships as a complete hub rebuild set, listed as the Turning Point Propeller 11500300 Hustler Hub - 503.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Turning Point Propellers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 11500300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Kit Number:\u003c\/strong\u003e 503\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Turning Point Propeller 11500300 Hustler Hub -
