Any numbers on the degrees of heat that Polysulfide or the
newer Polyurethane can handle without degrading??

I doubt it matter, Kelly. While running, the immediate area will probably be lower than ambient. There's a 200mph, fuel-cooled wind constantly flowing through it. There's the possibility of it softening from heat soak after engine shutdown, but that shouldn't exceed the running temp of the water.
