1985 115hp Johnson. Yes, that engine has two (2) thermostats, however for some unknown reason to me, they're called vernatherms.

The hoses that are attached to the cylinder heads are attached to the thermostat housing. Within that housing are the thermostats, water bypass valves, springs, etc.

You've misread my reply. Follow the hoses that are attached to the heads towards the center of the engine. The other end of those hoses are attached to the thermostat housing.
