It is designed for GM-based 262 cid V-6 MerCruiser powerheads across a range of model years and serial number ranges, including the 205, 4.3L (2bbl), 4.3L (2bbl) GEN+, 4.3L EFI (GEN+\/TBI), 4.3LH (GEN+, 4bbl), 4.3LX (4bbl), 4.3LX (GEN+, 2bbl), and the 4.3L\/LH\/LX\/LXH V6 Alpha (Gen+) and Bravo (Gen+) drive combinations. This rotor is intended for contact-controlled distributor ignition systems and is not designed for Thunderbolt ignition setups.\u003c\/p\u003e\u003cp\u003eThe rotor features a machined exterior finish and mounts inside the distributor cap, where it directs spark from the coil to the correct spark plug wire terminal as the distributor shaft rotates. It ships as a single rotor assembly (one unit per package) and is commonly replaced as part of a routine ignition tune-up alongside the distributor cap, contact set, coil, and spark plug wires. Sierra manufactures this part to meet or exceed the specification of the original equipment component it replaces, making it a straightforward direct-fit replacement for the applicable MerCruiser V-6 engines.\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 18-5432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Rotor Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistributor Type:\u003c\/strong\u003e Contact-controlled, standard rotation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Compatibility:\u003c\/strong\u003e Not for Thunderbolt ignition systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e GM 262 cid V-6, MerCruiser I\/O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999319319\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury Marine 13524A6, 13524A4, 13524Q06, 19405A4, 90576A5;
