I just installed a Powr tran Python on my 15hp kicker and I-Troll haven't used it yet but the the I-Troll is a lot faster than the pro troll x2. I have Garmin on my main steering and it dose a great job BUT I don't troll on big motors. The Garmin works great when running to and back on open lake my boat is a 27' Baha Cruiser catamaran. TR-1 are good units just didn't need another hydraulic component on the boat.
