As an owner of both Supercharged I/O's and 2.5 O/B's I can say with confidence that 105 is very possible with that much hp on that hull. The XR drives are a fast drive. On a cat XR's will run 150 mph easy with no blowout. They look like Sportmasters. As for a drag race... be careful guys when you pull up next to blower boat. Once on plane a supercharged boat will run very hard in the midrange all the way to top speed. I know every boat is different I/O or O/B, just do not think all I/O's are dogs. The right hull and the right hp will be fast, be it an inboard or outboard.
