The techs at Raymarine initially attributed the problem to low voltage, and then to a defective solenoid, part #M81167, which Raymarine says is out of stock and will not be available for 3-4 weeks.
I had the same thing happen on a new Simrad
drive, and got the same story on availability from them. Fortunately I hosted a meeting for the West Marine
product reps at he yacht club, and told my story to them. I got a call the next day from the West Coast Simrad
rep, who brought over a new drive assembly and let me swap out the solenoid and valve with mine.
The Simrad and Raymarine drives may use the same solenoid, and they probably know that there is a bad batch of them circulating. I am sure that Raymarine has many, many drives with spare solenoids sitting around, and that with the proper motivation they also can get you one tomorrow.
