Have a XR drive on a ITS box. Power is / was 575 SCI. Now Roller Cam, 8:71 Blower and Dart heads. Boat is single engine and very light (4600 Lbs,). How much HP is the XR take? What stronger drive will fit on a merc ITS?

XR is rated to 600HP

SCX will fit the ITS setup.. The 8.71 will be hard on the XR in the mid range.. Lots of torque available down low..

who builds the SCX? Immco?

yes

how much does a SCX typically cost? i guess i could get a decent price for my XR since it only has 60 hrs. on it

$15k will get it done.

I'm in the market for an XR, but I'm cheap, make me an offer
