This is the Sierra head gasket numbered 18-2946, listed with the OMC reference 908611. It is a head gasket for OMC engines, the part that seals the cylinder head to the block. The details given are short: the maker's number and the OMC cross-reference are what to match against your old gasket when you compare it with the part you are replacing.
Our take
The 908611 OMC cross-reference tied to Sierra 18-2946 is the useful detail here: it lets you match this head gasket against an old OMC part number rather than guessing by engine. Nothing about material or size is stated, so check it against the old gasket.
