Shp sensor fail

[mpo881]

So here is what I found. After doing some more reading, I felt confident that the issue was the stepper motor. I located one on eBay for $180.00. It arrived today, I installed it and tested it. Everything is working well. The only thing I cannot do of course is to check the targets on the screen as the boat is in a building currently. It wont be long though and I can do a complete test but I am glad that the stepper motor seems to solve my problem
Thanks
