I have spent the last couple of days trying to debug the side-power bow thruster on my boat, and the up/down 4 relay system.  My motor for up/down had a bad bearing and was blowing a fuse.  It appears to also have cooked a relay or two.

In my efforts at fixing, I redrew some of the electrical diagrams to make them a bit easier to follow, and thought it might help some of the others who have a similar problem.

Mine has the magnetic switches, instead of the pushbutton stop switches, and importantly, they are ‘normally closed’ switches, that open when the thruster is in the required position.
