Thanks for the input. I have an emergency rope for manual start. I've experienced that with a 125 horse outboard and it was a real bummer.
You are right ... a sonar & vhf radio won't draw too much & we probably wouldn't ever have both on for any lengthy periods of time either. I guess that my bigger concern would be over trying to figure out how long I could safely leave a "music" radio (and maybe the sonar) on while adrift fishing for example. With one battery, I think I'd always be playing a game akin to figuring out how low you can run the gas tank before the arriving at next station.
I've been getting quite brave in how far out I'm willing to go on a calm day (part of the reason I want the vhf now) & I'm thinking that I want the security of a dedicated (or isolated?) battery for starting purposes & want to find a simple and convenient way to keep both charged.
This is new to me so the learning curve is straight up. Would the following switch/set-up be an acceptable solution for this basic 2-battery set-up? & Does anyone know if my stock '97 Mercury ELPTO 75 can handle the chore of charging both in this set-up?
