Well I can't tell you that the M 120s are the ones you need but...
Once you have trim tabs installed and ready to use, there's a learning curve associated with every boat. While like models share similar weight and features when sitting in the boat yard, once someone owns one that starts a whole new set of rules. Everyone is somewhat different and the same can be said about boats. How many people on board, fuel, food, bait, beer? You get the idea so.....
You need to work through the various combinations of BOTH tab settings and motor trim. That isn't something right out of the box but takes seat time in varying sea conditions under different loadings. The auto feature is designed to be set ONCE you establish your best running trim. The module adjusts to movements in the boat and sea conditions and IMHO performs best during long runs in moderate seas.
So to get the best from your investment, be prepared to "play" with your new toy. The best part is discovering where you boat "feels" the most comfortable, backed by your performance indicators i.e. the tach, GPS indicated speed and fuel gauge/monitoring system. The "correct" setting are the ones you find for your boat. LED indicators are nice (unlike some, I like them) but they just help you get a starting point quickly, afterward you need to tweak the tabs and trim to get it just right. You may be surprised at what the LEDs look like when your really running smooth.
Good luck.
