I thought I should be more specific. I do not troll on my big motor but the way my steering it set up I control both my kicker and rudder from the helm on the same steering wheel. It works very well. What a liquid tie bar dose is essentially like a mechanical type tie bar like you use on a outboard to a kicker motor only it is for hydraulically steered boats. What ever my rudder hydraulic cylinder dose my kickers hydraulic cylinder dose which lets me utilize the AP for the kicker as well as the rudder. It also makes it very nice when its really windy to help with boat control around the docks. This is just one option you could use. The tr1 gold works very well also. Just a way to save money on setting up your rig and you will have AP when your up on plane with the big motor or trolling with the little motor. It works very well and I have been using this set up for 3 years now with no issues yet (knock on wood)! I also mounted my kicker in the center of my transom rite in line with my rudder. NO issues with netting fish of either side of the boat! Even when 5 or 6 are coming in at once! I will be putting the boat in this Friday at channel grove marina if you are close to there and want to come check out my setup just give me a call.
