I changed my thermostat last year. Like yours it was weeping at the housing and when I opened the cap..the thermostat and both its seals were disintigrating..along with the thermostat its self.
One was a rubber ring type washer that fits round the thermostat..the other just a gasket that you could cut if you wished. (The kit came with two cut gaskets..one a different shape from the other and I discarded the one that was not for my model)
I ordered the parts from Black Dog Marine.. and I got it next day
Here is the part that was for my engine..25hp Mariner.. it will be the same for the Mercury 15hp ?
