Thread: GT Kontiki Steering issues

Hi,
I have an older GT Kontiki that up until now has worked awesomely. Now something has gone wrong with the steering or electronic compass. I set the bearing and start the motor the rudder starts rotating. If i change the heading of the kontiki the rubber will rotate in the opposite direction.
it seems that the compass is still doing its job but the steering module has stopped functioning properly.
I do not know what the inside off the GT looks like or exactly how to take it apart to get to the steering module.

I have spoken to the guys at GT and they have told me $500 to replace compass and steering unit. I would think that the right parts would cost $20 off alibaba?

Can anybody help or suggest how to fix it. I was even thinking that a GPS unit could be retro fitted?????

Thanks
