No sorry. I just bought 2 with the same dimentions as mine, they fitted & worked fine. If I remember correctly I had to change the electrical connection fittings which is a 2 minute job.they had calibration instuctions with them but did not need to be altered. Engines were AD41b's boat was a Fairline 33
