Sierra 18-7918 is an oil filter made for 4-cycle outboard engines, and is also known by the shorter name Sierra 7918. For which engines it fits, the maker refers you to its application guide with complete application references. Look your engine up there before you fit it, because the filter's own description gives no engine list.
Our take
This is a 4-cycle outboard filter, and that is nearly everything the maker states about it: no thread or size is given, only a pointer to the manufacturer application guide. Get the fit from that guide, not from the part name.
