    What year is a 7520?  You must be very careful here.  You mention a 1957 7.5hp, which is a 7522.  The base gaskets changed in 1956.  Basically, if your engine has the spring mount system it uses one style gasket.  The other gasket is used if your engine has rubber mounts.  Using the wrong gasket will create a problem.  Post a picture of your engine, or determine what model year a 7520 is…

    OK, just determined that a 7520 is a 1956 model, which has the rubber mounts.  So, the proper base gasket is:

    OMC/BRP:  304314
