The master relay I have installed getting very hot.



I think you do have something wrong somewhere.  The data sheet says it will handle 80 amps continuous.

Check the drawing at http://www.aircraftspruce.com/catalog/pdf/11-03161draw.pdf  to insure it is wired correctly.  The battery source should hook to the "BAT" terminal, the other terminal to the "load" and you "ground" the coil terminal to energize the relay.

An yes, for the price I'd get a new one.  No way to tell what damage the heat has caused.  You don't want it to fail at some point in flight.
