Took the boat out for the first time with my smart tab install... seems like they actually do what they claim. The bow didn't rise at all when accelerating, no porpoising and boat is easier to control at low speeds.
My Q4 smart tab installation looks different than some of the others on this board. Do I have the 19' Q4 hull instead of the 18' Q4 hull? I'm wondering if my Q4L stands for Q4 "long" as mine was produced around the time they switched hull designs.
