That confused me (NO SMART remarks!).

I have an accessory switch on the console also. But the only thing run through it is......um....I think the plug for (duh) accessories, like a car phone charger. It doesn't turn anything else on or off. That's how the boat came.

And why would your depthfinders not have an on/off switch. That's what is throwing me. Sure they do. So not sure what you mean exactly. And why would you want to turn those on every time? There are settings and it has built in GPS and has to 'find' the satellites all over again, and all that. I don't want them to go off and have to reset the right 'view' and other settings. Besides, I want to know what's under me when I start the big motor.
