How are you running the engine, on a hose or in a barrel? With the lower unit off and the thermostat out, attach a hose to the water tube and check the flow through the block. If you have good flow, you might check the head gasket. It is possiable for a head gasket to leak compression into the cooling system and cause it to overheat.

Seems like if water was definitely getting to the thermostat (assuming you had the cover off?), then it wouldn't be in the lower unit, so no sense taking it back off. Is the motor still getting hot, is that why you think the impeller isn't pumping? Or is there a tell-tale on it that's not showing water? Daviet is THE man, so follow his advice as he's helped me over the years. I'm just one of the "extra question askers" around here, lol. Welcome to iboats, btw.
