Tooner, I have same motor, water pump impeller and thermostat were all that I could find in 2017, that after several years of looking/waiting. Even then, key way was not available, had to "modify" the new impeller key way slot to accomodate it. But it's been working find since... Aggravating to have a good motor and very limited parts availability. So much so, that when I have to buy a new motor (and it could be for the simplest failure), it most likely will NOT be a Tohatsu.
