I've had one mounted on my 8hp Honda and it has worked great so far. Only have 30 hours on it though. Did have a some difficulty mounting the gryo bracket but solved the problem by drilling a new hole in the bracket for one of the mounting bolts. I also can't seem to remember to turn the darn thing off at no fault of the Trollmaster.

I also contemplated purchasing the TR-1 but decided to buy the Trollmaster and then a Raymarine Auto Pilot for the main at essentially the same price. With the motors linked I have the same effect as the TR-1 but gain the auto pilot for the main which is an extremely effective aid especially when cruising in the dark or fog.
