Hello, The 2001 Horizon 76 I purchased in Florida made it to Ensenada on the big ship just fine and we're now working our way up to San Francisco, currently docked here in beautiful Santa Barbara. Great trip so far. One of the first things I need to figure out is why the autopilot, when engaged, is transmitting a significant amount of noise back to the helm. Here's roughly the setup: The helm station (single helm, in the skylounge) has three hydraulic lines that run down, via the ER, to the lazarette and the steering rams, as expected. In the ER, each of the three lines tees over to the autopilot pump. When engaged, the wheel at the helm is disconnected (can spin but has no effect; does not spin by the AP), and the autopilot maintains the heading, as expected. Also in the ER is the reservoir, with the system pressured via a Shrader valve on top. What's not expected, and pretty annoying, is the whine being transmitted up to the helm. It's not so loud that you can't talk over it, but it's impossible to ignore. About every second, as the AP makes adjustments, there are whirs and whines of the pump operating. I'm assuming that this isn't how it is supposed to work, as I can't imagine someone taking delivery of this boat when new and accepting this. This did show up as a survey item, but no reason offered at the time. Any ideas on what may be causing this? Thank you!
