I have installed the Ride 450 on my 2019 C248 w 300hp Yamaha..I regularly cross the Straight of Georgia from Vancouver to Vancouver island. This system is a game changer for these hulls. Fuel economy virtually unchanged and much less on off the throttle to manage conditions, easiest way to describe it is she rides 3 feet longer and 1500lbs heavier and the dreaded rolling motion with any beam seas is really muted. I love this boat and have tightened her all up and trust her but I was on the fence keeping her just because the way she rode was very fatiguing in rough water. I would say it is worth the investment for these hulls!
