I need to run wiring from my bow to my battery for a HDS live unit. What gauge wire is recommended for this?

10 gauge minimum.
8, if powering a distribution bus.
Be sure to use wire for direct current, preferably marine rated wire.
Impossible to answer with the information provided. But if you read this, you can answer it yourself: https://teamcolibri.blogspot.com/202...r-my-unit.html
I'm running 2 Carbon 9's, AT, and a Rite-Hite up front. I had developed low voltage issues with my original installation. I recently ran 10ga "SO cord" from my 100ah Lithium to the bow and it worked 100%.
Here is a guide

Here is a guide, do not exceed the wire sizes recomended

How's that? Elaborate on specifics.
Most on these forums have gone way overboard on wire size, to the point of protentional negative effects. You gain nothing by going to larger wire than what I recommended.
For bass boats done as suggested there will be less than a three percent voltage drop tops with high quality wire and no runs longer than 30 ft round trip

Will support 22 amps of current draw, with that design on any bass boat at 3% voltage drop properly layed out to avoid excessive wire length. Fuse box should nbe located very near or in consol area center of boat
4 hds 16 plus active target. With 5 % drop somewhat more which is still quite acceptable.

Good information from both of you experts. Thanks for sharing!
Blue Sea Systems 5033 ST Blade Fuse block, amazon has them
Dont buy the cheap ones, Bussman or Blue seas (both the same units)
They do have others that have more than 6 fuses if needed
Thank You Leon Pugh
Also recommend Blue Seas. I’ve installed them in a couple boats. Very robust. Get the right size heat shrink ring terminals.

another Blue Sea rec, have one at bow and one at console, fed by 8ga direct from battery. Fuses easy to access (no inline fuses bured under panels) and wiring clean and easy to manage.
Just did 6 gauge to a blue seas with 12 gauge to 4 units, mega 360, and active target. Reading 12.8 at every unit all day
Blue Sea for me... Second time installing one plus wiring for me. Have a 25A Blue Sea breaker installed on the main power supply. My boat has a nice surface under the console where I mounted it. All Kimbluth wire from Amazon. NEMA and Front graph power supply wired directly to the left side, right side is power supply to front.
Picture was taken a little off center, trust me... the fuse block is centered!
