No need to change the carbs. They can be adjusted. Send them to Nickerson or Pro Systems if you don't think you can do it. Mirages always slip a lot. Changing to Bravo 1's will make a world of difference. You'll pick up 5 mph at cruise speed. Probably even make it run faster as it will trim better. Your speed is only off by a little bit. New, that set-up ran about 67mph under ideal conditions..

I had one with 330's. Swapped in a pair of 420's and picked up 8 mph. It was a fast boat in back in 1986.
