    I want my stereo in my boat not to shutdown every time I shut down the motor. When you are pulling skiers you shut the motor off in between skiers but my stereo shuts off and takes a while to repair with my phone when I switch back to ACC.

    I have a 12V constant supply to the stereo and a 12V remote wire. What I want is the 12V remote power to feed a relay to start the stereo and when you turn on the power the remote feed to the stereo stays powered for X amount of time when you shut off the boat. If start the boat then the timer should not stay on and not start until the boat is shut off again.
