Just bought a 2004 30 eliminator with 525's and the boat has xr drives with extension boxes. I wanted to know if anyone knows best set up. What size shorties and props work best.

With twins you can run a higher X. I would think you should be able to run even with or one inch above the lowest point of the bottom. ( about 10 inches forward of the transom.) And a Bravo 4 blade seems to work the best in that application.
I am running one inch above with an IMCO -3 shorty with a 30 labbed Bravo 4 blade.

Any pictures???
