Hey
Ok so on my 4.3m tinny, I have one battery stored at stern that powers the nav lights, sounder and bilge pump. My 40hp 2 stroke yammy outboard is a pull start so it doesn't require any power to start. There's an alternator that charges the battery.
I'm getting a electric motor on the bow and am torn about where to put the secondary battery. My question is - given my outboard doesn't need power to start, can I get away with using a single battery to charge the motor + all the above mentioned electronics? Not sure what my current battery is, it's a few years old now so I'd be happy to replace it with something with lots of juice.
Cheers,
