on my boat (although it is branded NKE). I picked it up last year on E-Bay and matched it to a Simrad AP. Both are very nice pieces of kit and the drive appears very well made. I'm only a coastal cruiser but I found it to work very well and never used my Monitor at all this summer since amps were not an issue.
I did the install myself and it all works fine although it was difficult at times due to access issues.
