Just one thermostat in there. The other thing's a 'venostat', keeps the pressure in the block constant. Make sure you don't mix up the two springs.

Man that was a pain in the rear. Definately not mechanic friendly.<br />Here is a stupid question.<br />Do most thermostats stick in the "open" position on outboards?
