Stern thruster failure on a 2020 R29 CB

[R29 Genansi]

Stern thruster failure on a 2020 R29 CB - Two days ago, my stern thruster was intermittent. Today it is not responding at all (no motor noise). I read on the forum a possible solenoid problem. Where do I check that and what are other possible causes?

Intermittent tells me it might be a corrosion issue somewhere? If the solenoid fails, it probably wouldn't come back.
