I purchased a TrollMaster remote throttle control unit in June 2016 . It worked beautifully for the summer, but the servo motor stopped working in August in 2017... two months out of warranty. Well-- a replacement servo was not expensive so I ordered a replacement from MarineTech Products in Minnesota. Got the new one and installed it-- DIDNT WORK! I phoned MarineTech and gave them my sad story. I followed a check list that was giving over the phone, and I had done everything to check the unit on my end. Upshot..." send the WHOLE system back to us and we will figure it out for you. " I pulled all the wiring and the controller and shipped it down south. Ten days later a brand new unit shows up with the message from their tech: They tested the whole system-- and there was nothing wrong with it--- except-- IT DIDNT WORK!!!! They replaced the whole system servos, controller and wiring under warranty even though it was two months past the warranty end date. Now thats almost as good as a Scotty warranty ! Nice to see that kind of customer service.
