Re: IMCO lowers how much faster?
I had XZs on my boat with HP 500 ran 93 without a problem, upgraded power (725hp each), the boat would run 99mph about 5000 rpm increased rpm to 5600speed dropped to 96. Added Imco lowers and ran 110 mph. Another boat lost 3 mph because the props had more bite, with different props picked up two over original speed. These were standards not shorties
