Re: Do I have a thermostat

Some do, others don't, depending on year. If you do have a thermostat, it's built into the exhaust manifold cover on the Port side of the powerhead.

There's a casting for the 'stat at the top of the manifold. The thermostat cover is held on by a snap-over spring-thingy. Thermostat directly under that cover.

If you don't have that, you don't have a thermostat.

Here's a parts diagram showing a manifold cover equipped with thermostat:
