What kind of HP numbers for mecury 525's
Has anyone actually dynoed these motors or have known people to have dyno testing done on the 525? If so what are the actual numbers hp and tq, and are they pretty flat across the board? I've heard that Mercury underrates these motors is this true? And what is the easiest way to get more power out of these engines? I know a blower is always an option but it doesn't look like there are to many companies( Whipple maybe Procharger but haven't really seen anything from Procharger for this motor though) that have kits for the 525 a lot for hp 500's, but not for the 525's. What kind of reliable horsepower after a blower is added.. What about porting of the Edelbrock heads any power there or computer reprogramming?
Thanks for your time. Mike |

They will vary from 538 to 557HP from Mercury.

Early numbers from a number of manufacturers don't seem to justify the price of the 600 over the 525, but everyone is trying to get the setup right so far, or at least that is what they are saying. It would be interesting to know just how much HP those 600s are putting out.

Thanks JC. It will be interesting to see how soon they do this. I am probably 2-3 months from having to make my power decision.
