I changed to a ball valve on my SD50 and regard it as a very important upgrade.  The valve is accessed quite easily through the engine hatch in the port cabin without engine heat being an issue.  However, I would never consider automating such thing as a seacock on an H400; I need to know if they are open or shut and the only way to know this with certainty is by manual operation.  Automation introduces more complexity and potential points of failure on safety-critical items and on a H400 I can't see the gain. Sorry!

My ‘automation’ solution is to fit a wing nut socket to a power screwdriver (torque setting needs to be about midway). Works a treat for opening & closing the gate valve seacock’s T-handle. I set out to replace the gate valve 10yrs back (after buying the boat with it seized), but instead cleaned up the internal thread with the right size tap & regreased. It’s worked ever since. Just needs exercising regularly. Hence the power drill ‘support’. I open and close it each trip.

TRU Design offer a fully monitored solution using position sensors on each valve, it wouldnt be a big step to create a 'one close' for all valves...
