I have a Troll Master Pro2 on mine.
This is the 2nd boat I have had it on.
Love it.
The standard remote throtle for a kicker is only good to start the engine and trim it up/down.
Or maybe if you want to run the kicker up at higher speeds, like in an emergency to get back to the dock.
The resolution for dialing in your speed with it for slower trolling speeds sux.
Any of the available kicker speed controls are far better than the standard throttle, and this includes a tiller throttle.
I base this staement on having owned 11 boats with kickers since the late 70's.
Sorry that I cannot comment specifically on the Itroll.
