Sierra 18-5362 Distributor Cap for GM V6 Module-in-Cap Distributors, Replaces Mercruiser 850484T, OMC 3854331
The Sierra 18-5362 Distributor Cap is a direct-fit replacement cap designed for New GM style "Module in Cap" distributors used on V6 marine engine applications. It mounts to the top of the distributor housing and routes ignition voltage from the internal module to each spark plug wire in firing order, so a cracked, arced, or corroded cap is a common cause of rough running or a no-start condition. This cap is built to the fit and function of the original equipment part and is interchangeable with a range of OEM and aftermarket cross-reference numbers used across GLM, Mallory, Mercruiser, OMC, and Volvo Penta ignition systems, making it a straightforward swap for boat owners servicing GM-based V6 marine engines with a module-in-cap distributor.
The cap has a white, machined exterior finish and a twist-on closure for secure, tool-free installation once aligned to the distributor housing. When replacing this cap, use the matching Sierra 18-5408 rotor to complete the ignition module service, since cap and rotor are designed to be serviced together. Each Sierra part is built to meet or exceed the performance of the original component it replaces and is backed by Sierra's standard limited warranty.
