Default 22 Sea Hunt - Wire upgrade

I'm redoing some of the wiring on my new ( to me ) Sea Hunt. This is a first time an a project like this. Any suggestions or corrections welcome !

I'd suspect most everyone is different. Just make sure you run large enough feeders to your terminal blocks and work from there. Use marine grade wire. If you really want the job done right solder the connections and when you're done spray everything down with Corrosion Block or Alumnox.

I went with breakers over fuses on my rewire. Easier to reset on the water than to fumble to find fuses and change them!

Good comments. I hear more and more about not soldering in Marine environments due to "hard spot" deterioration. Gotta get a good crimper.

bildge pump auto power should be pre switch so they will run with the switch off. you can get manual switch power from the helm if wanted.

I would ditch the 1/2/all switch for a blue sea add a battery kit. with better switch that isolates the batteries and acr.

I've never used an ACR. makes sense...

Yep, I've heard both schools of thought. I choose to solder the important connections then use a premium heat shrink.

If I don't solder then I use Alumnox or nolax on the wire then crimp. It makes for a messy connection but will provide corrosion resistance for several years in a salt environment.

BEP 716 battery cluster for single engine, which includes a built-in ACR - Automatic Charging Relay.

Some of that wiring diagram looks familiar That's cool, as another THT'er provided the base template that I used as well

Lots of design options & choices you can make - I'd agree with the recommendation for an ACR type switch setup - that or if your motor has an Aux charging cable, go with independent switches for the two batteries , and then a switch to allow you to parallel them together - anjust make sure you properly size the wires and fuse them with the right size & type of fuse.

Need fuse on the auto bilge pump - I used blade fuses in a BlueSeas in-line water-resistance socket

Have you run the numbers on the voltage loss for your critical or sensitive circuits to ensure that your wires are sized sufficiently large - they look large enough for the loads from a safety perspective but you also want to make sure that you don't have too much voltage drop.

Looks pretty good overall..... good luck with the project.
