I have a 19' 1986 Chris Craft Cavalier which I recently installed Smart Tabs on, ST1290-60. They worked great my first time out when it was me, my wife and two girls (ages 2 and 4). The next time I took it out I had the 4 of us plus two more adults who sat in the very back of the boat. The boat has a Merc 140 so it isn't the most powerful thing around. With them in the back and the Smart tabs I was still getting a lot of bow lift. This was with the suggested starting settings on the tabs, lift pressure #3 and angle at 25 degrees. What would you suggest I go to next to fix this problem. Should I adjust one or another or both? Thanks in advance.
