This Sierra thermostat kit, 18-3608, is listed for Yamaha engines of 115-225 hp. It replaces number 6E5-12411-30-00. A gasket, number 688-12414-A1-00, comes with it, so the seal for the housing is part of the kit rather than something to source separately.
Our take
Gasket 688-12414-A1-00 is included with the thermostat, so the seal is covered when the housing is opened. The kit replaces 6E5-12411-30-00, which gives a number you can match against what is already on the engine.
