Spa pump leaking, gasket?

Just purchased a house and trying to learn about the pool/spa. Really some quirky issues with many parts, but here’s the first of mine to tackle. The spa pump, motor C48L2PA105, pump MPRA6F-148L (faded, but I think thats correct). It seems like a gasket, but the connection between the two (connected with bolts) is leaking. I have attached a photo for reference. What part number would this be? And could it be the gasket, or possibly more serious?

Thanks!

Welcome to the community D_Baz! It is most likely the housing gasket (5057-06)
Make sure the gasket is properly seated after putting on the new one. Make sure not to over-tighten the bolts, or you could strip the housing. We also have a full tune-up kit for both Chlorine pools (GOKIT47) and Salt pools (GOKIT47SALT).
