I run a 15 hp kicker on my 30' sport. I have a liquid tie that links my rudder and kicker together. It is controlled by a raymarine evolution AP. I have no issues trolling with it and the AP works great. I also know a captain that ran a 272 with a yamaha 9.9 with tr1 gold with no issues. What I like about my setup though is you get AP while cruising as well and there is no need for 2 AP's. Call me if you have any questions. I would be happy to answer any of your questions. 7403417894
