This is a Sierra thermostat, part number 18-3540. It is cross-referenced to Yamaha part number 6E5-12411-30-00, so that is the number to compare against the thermostat already in your engine. The only identifiers given are those two numbers. No opening temperature is stated, so confirm that rating against your engine's specification before you rely on it as a match.
Our take
The Yamaha cross-reference 6E5-12411-30-00 is the useful handle on this Sierra 18-3540: match it against the number for your engine before anything else. With no opening temperature stated, that number is the only way to confirm it is the right one.
