Every time I restart my boat the stereo system is reset. This causes the volume to reset to its default level. Is there a way to keep power to the stereo when the boat is starting?

The reason for your radio resetting is because you have the radio power attached to the same place the engine power is attached. So when the radio voltage drops lower then the minimum limit, it has to reset the processor and everything starts over again. Two ways you can stop that from happening. First get another battery for the accessories and one for the engine. OR find a battery that can both start your engine and still have enough power reserve to maintain the voltage level. The fact that your voltage is dropping so low could be a sign of your battery going bad or being too small to run everything...

Re: stereo volume resetting

I have a similar problem with my Humminbird unit. At times (generally at the end of a day of fishing), starting the motor (Yamaha F50L 2011), the voltage drops and freezes the screen. I get around it now by shutting down the Humminbird before starting but that's a pain in the butt.

Are there limits on how large a battery I can use on the main motor?. My owners manual gives me minimum specs for Cold Cranking amps and Marine Cranking Amps and Reserve Capacity. I don't really have space for a second battery, so a larger main could be a good solution.

No, there is no maximum, except for your available space and money. But first make sure undersized wiring and/or bad connections aren't causing the problem. Maybe reducing the low voltage warning level on the HB would help, too.

Thats what I was thinking a bad connection often causes that sort of a problem.

Re: stereo volume resetting

There could be another way to solve this situation, but it requires a few electronic components. Install a directional diode inline with the positive supply line going to the radio. That is the cathode (banded side) to the positive radio inlet side and the anode (non-banded side) to the positive terminal on the battery. And after that steering/blocking diode is installed, install a very large (Farad size) capacitor on that same side as the radio is connected. Then when you do crank up your outboard the voltage can't be drawn back to the engine from the radio setup and the large capacitor could keep the voltage level up for a few seconds... Hope this is understandable... :facepalm:
