Thread: Dif. between...

  1. #1
    Other than the obvious HP #'s, what is the difference between the Merc 525 and the 575. Maintenance? What about $$$?

  2. #2
    The Merc rep at the show said the 575 is about $10k more than the 525. Also the 575, as I'm sure you're aware, comes std. with a supercharger and does not have closed cooling whereas the 525 does.

    The 525 comes with aluminum Edlebrock heads and tuned port injection. The 575 has iron heads and throttle body injection on top of the 265 mini blower.
