Switch portable fishfinder to permanent and battery?

[Raycaster]

I have a Portable Humminbird 160 that I want to permanently mount on my used 16' pontoon.

 

I have no problem mounting it but wondering about the power supply.

 

The fish finder battery I have lasts for days without needing recharging so hoping I can simply add to the accessory panel (separate switch and fuse).

 

I have an older 30hp Yamaha that I assume recharges the battery when running so would the fishfinder be a huge drain and require another battery?

 

I could just put the fishfinder battery in the console and use if needed...

 

 

 

Almost there...

You'll be fine with it wired into your existing panel/battery.

No problem hooking it to the boats battery.

For a fuse all you need is a 3 amp.

It will take for ever to drain your boats battery even if your motor didn't charge it.

I used to use a group 24 battery to run my big Lowrance depth finder up at the lodge and I would only recharge the battery (our motors didn't have electric start or charging capabilities) every 2nd or 3rd week.

Thanks guys for the quick replies.

Awesome, bought a 6 switch panel with fuses to clean up the wiring.

 

Just have to:

 

rebuild console

Rewire basics

mount furniture

 

Maybe a quick run on the Grand for a test with week...
