Unfortunately, I too have had to visit Robby on a few occasions. Trolling motor shafts tend to bend at odd angles when coming in contact with rocks and stumps at high speed. He always provided fast, reasonably priced service and advise. When I first bought my boat I had an issue with the trolling motor shutting off after only a few minutes use. The problem was the breaker fuse was too small. Robbhy said to put in a larger breaker fuse ad it has worked great ever since. He could have charged me for his time and advice but did not.
