Sweet, you can get Yamaha this year! Could not get them anywhere in the country in 2018 when I was shopping. I'm happy with the Suzuki, but love the lighter weight of the Yamaha. Looks like you went with a 200, is that right?

Also, I'm very curious what you're up to with the wiring from the fuse block to the terminal strip - why take up all that space instead of just running the field wiring to the fuse block directly? On every boat I've worked on I'm always fighting for space. Nice looking wiring...you must have something up your sleeve.

I’ve been told that the reason for the strip is easy diagnostic check. I am following a diagram I found on “new wire marine”. By the way What size wire did you run to your panel. How many amps were you going for? I think I can get by with 60 amps to the panel and not even use that.

Interesting - just a suggestion, before you get too far along, be sure you will have enough space for whatever electronics/electrical equipment, gauges, etc. plus plenty space for wire runs before you get too far along. I personally see no advantage to the terminal strip, it only adds wire distance and terminal connections, all of which add to the complexity, time to install, takes up valuable space, and also adds expense.

I ran #4 wire to the panel and I'm happy with that choice. Heater, fridge, 3 wiper motors, all the electronics plus relatively long run justify the wire size.

Sure wish I had a heated boat shop to work on, I'm itching to get into the final outfitting!

Is there end all be source for wiring a boat?  It won’t be long until I need to do it.  I don’t have any experience in this department and would like it clean and simple and semi expandable

Todd,

You can make it simple as you want, blue seas has support and diagrams.

I am using circuit breakers on the pot puller, windlass and downriggers.

Wiring: Both makes custom battery cables:

This ebay seller :  https://www.ebay.com/str/Genuinedealz?_trksid=p2047675.l2563

Just get a ratchet style crimper and marine grade shrink terminals, Some people use flange fork terminals but I really like the snap fork terminals, they get a little narrow and you just push them on the stud they will snap in place and stay.

There is a ton of info others who have done amazing jobs wiring, you should check out Dan Boccia's thread for more detailed info.

Rbob, I have tried to avoid it because I am not a big reader but I have stepped back and started reading Nigel Calder’s  “ boatowners mechanical and electrical manual” . There is so much info when it comes to electrical you need to understand why you are doing what you are doing. Lots of videos on utube as well.

Dido on the books, I have that one and the 12v bible. 

No way to avoid it!  lol!  Unless you pay someone else to do it.

Dennis, I am positive that reading Calder's book and understanding his message is going to result in a lot of time saved. In particular, understanding how batteries charge and discharge and why, how to size cables correctly and conservatively to avoid risk of an electrical fire (including bundling, temperature rating, voltage drop, understanding ampacity), how to protect the wires with fuses and breakers and why, how to avoid electrical interference with electronic equipment, and finally, the importance of good terminal connections so you can avoid corrosion and again have a safe boat.

I remember slumping down in my chair in mild frustration, going back to that book, and realizing I had all the info I needed all along, I just had to take the time to read it and understand it. Keep tweaking your design sketches as you go. Keep your credit card in your pocket until you're confident your sketch reflects what you really want and is safe and convenient and you have the components selected that best fit your needs.

As we discussed, Jeff Cote at Pacific Yacht Systems has fantastic youtube videos on boat electrical design and installation, including solar. Those videos really cemented some things from Calder.

One resource I have not yet mentioned yet is the "Marine How To" site, which has some of the best info I've been able to find on the construction/installation side of things - what makes a good crimp connector, what tools work the best, how to get a good crimp, etc. Especially this page:

https://marinehowto.com/marine-wire-termination/

Finally, I recommend ordering the current Blue Sea Systems catalog. It was very helpful to have the whole catalog on hand rather than going to the website all the time. And as I mentioned to you in private, I've grown very fond of their Circuit Wizard phone app....but was only able to use it confidently after reading Calder.

I know Brian has talked about putting together a basic electrical schematic for folks, but we all use our boats so differently, and electrical is such a safety issue, that I think if we're going to wire the boat ourselves, we need an education.

You're doing awesome everywhere else, once you get on step with the electrical fundamentals your electrical system will be on par with everything else you've done!
