You didn't read it properly.The 525 boats are twice the weight but not twice the HP.Also the majority of 525's dyno@ 470hp.

I don't know what your circumstances were with the condition of the sportmasters to begin with and the type (s) of hull that you ran them as well as what pitch props and your level of abuse to them.
My experience has been outstanding with the fatshaft 1:87 sportmaster lowers on the 2.5's.

(Amsoil and Alisyn gear lube help) However once you go to an inboard setup with #6's I don't think you'll go back to outboards! Outbords def give a great bang for the buck, But 710 Ilmors with #6's are a whole different animal!
