Leaking somewhere

[3FootPool]

I cannot for the life of me figure out what is causing wet spots around my pool pump and filter. I don’t see any leaks or feel anything wet on the pump or filter. I have checked both drain plugs and the strainer cover/gasket on the pump. I’ve also checked all piping as well as the filter’s drain cap/gasket. Where else can there be leaks?

My guess would be the shaft seal on the motor. It would slowly leak and drip down into the bottom of the casing and find a place to escape onto the ground.
