Default Fishfinder electronics problem, driving me crazy

I've got a Raymarine DS500X fishfinder. Every time, or almost every time I start my outboard engine (Johnson 175 hp 2 stroke) the fishfinder shuts off. Sometimes it starts eight back up, sometimes it does not. The hot wire from the fishfinder was attached to my accessories switch, then I changed it to my electronics switch, no change. I'm almost to the point of running a wire directly to the battery but I don't want to do that because the fishfinder power wire will stay hot ever after I turn off the battery switch.

Any suggestions, this is driving me nuts!

I had the exact same issue with my HDS-10. UNit would shut down when I started the engine. Solution: The Sounder requires a minimum of x volts to work. I found I had a bad power cable to the HDS which caused the voltage to drop when the engine drew current fromt the battery to start. I changed the power cable and all is gr8. I was initially worried thinking it was a poor battery and as I did not want to get caught short with a flat battery I really needed a solution. The HDS has a <12v alarm on it that used to sound that also alerted me to a problem. Good luck.
