Cross-referencing an oil filter
Oil filters cross by number. Sierra 18 series filters print the OE number they replace right in the title (18-7824-2 replaces 35-866340Q03, 18-7918 replaces 35-877769K01, 18-7916 replaces 0434839), so match to the number on the old filter rather than the engine model year. EMP and Quicksilver list their own equivalents, and Mercury Mercruiser parts carry the 35 prefix.
Filters differ in thread, gasket diameter and internal valving, so do not substitute by can size alone. Several parts here have a Case of 12 option, worth it if you run more than one engine. There is a diesel filter in the line as well, Sierra 18-0035, not interchangeable with the gas engine filters.
