Hey John, have had my smart tabs about 6 months now, and they have exceeded all my expectations. My boat takes off like a rocket, no bow rise whatever and handles great. Due to space considerations I had to mount them closer to the motor than you recommend, but this has had an unexpected benefit. At speed the smart tabs put up a 6inch wall of water right at my prop. This, coupled with my CMC trim and tilt has allowed me to raise my motor and trim my prop higher than the bottom of my boat and not lose bite. Are you aware of this benefit? For shallow water it is phenomenal, I ran across a 2 inch deep flat the other day by accident, I hit the trim till I had a huge rooster tail and never slowed down. Just thought you and others might be interested in this unexpected benefit.
