The size of the engine is not mentioned, but most Mercury outboard models situate the drain plug on the lower half of the port side cowling. Have your funnel and or drain pan ready when you remove that plug! Also be careful not to drop the sealing washer off of the plug, fwiw, the manufacturers recommend replacement of this washer.

Take the engine cowling off the motor. The thermostats are housed right on the top of the engine towards the back. The housing is black and has 3 bolts to romove. There are 2 thermostats, each is a different temperature so be sure to get the correct ones.
the thermostat is located behind the timing bet cowling. it is a bear to get off. i changed the timing belt and everything in there when i got it off. too hard to get off to have to do the job twice. the probem is that you cant get to the bolts and there is about 9 of them. i also changed the water pump.
I'm pretty sure u remove the cowling from the front and it shall come off in 2 piece's to get to the part u suggest u may have to remove the exhaust manifold
