AQ\/BB Series","description":"\u003cp\u003eThe Sierra 18-8510 Exhaust Elbow Mounting Kit is built for stern drive engines using the Volvo GM Small Block V8 305-350 cu.in. Platform, covering the AQ and BB series listed below. This kit supplies the hardware needed to mount the exhaust elbow to the engine, giving you a clean, correctly torqued installation without hunting down individual fasteners and gaskets piece by piece. It is designed to be used together with the matching exhaust riser, part number 18-1909-1, so the elbow-to-riser connection seals properly on reassembly.\u003c\/p\u003e\u003cp\u003eBecause this is a mounting kit rather than a single component, it is intended for engine rebuilds, exhaust system overhauls, and routine maintenance where the elbow is being removed, resealed, or replaced. Using the correct mounting kit for your specific engine family helps prevent exhaust leaks and water intrusion at the elbow joint, both of which can lead to more serious engine damage if left unaddressed. The kit carries Sierra part number 18-8510 and is identified by UPC 808282126902 for easy reordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-8510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Elbow Mounting Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine:\u003c\/strong\u003e Volvo GM Small Block V8 305-350 cu.in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e AQ and BB 200, 205, 211, 231, 225, 260, 271, 290, 311, 500, 501, 570, 571, 572\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With Exhaust Riser:\u003c\/strong\u003e 18-1909-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282126902\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo GM Small Block V8 305-350 cu.in.
