Irvine same mount. dimensions as 46 SF/FX??
I thnk the Irvine has the same dimensions as the .46FC.
I have one mounted on a Cloud dancer and it's an amazing engine. I have a 11x7 and it hauls like crazy, If yu want all out speed try a 11x8 or 11x9 if you want speed ans traction try teh 11x7 or 12x6
