Boat electronic wiring diagram 

New boat owner just watched you video. Simple, clear, most of all informative. Thank you for the lesson!

Thank you for a very well presented video on boat wiring. I have a used pontoon damaged in a storm. I am working in putting it back together including fixing the damaged wiring. You method of illustrating the wiring connection was simple and clear. A simple ladder diagram at the end of the video would be a bonus. Thank you

This is a fantastic video. Thank you. It helped me put in a new fish finder and made it very simple for me.

Joe, I can not thank you enough! We are a small fishing channel who hopes of getting on the water to provide better content, and we have been struggling like no other on restoring our old 1970s trihaul. This video has helped explain nearly everything that was confusing us, and we just wanted to give you a big thanks for making this!

I need to say thank you for simplifying this manufactures nightmare. The factory diagram left me scratching my bald head and reaching for the aspirin, long may you run Sir!

Very nice, very clear and simple! Having been knee deep in re-wiring my boat over the past two weeks I will say the installation of two fuse boxes (one for ignition power and another unswitched power to run devices while the engine is off) is of paramount importance. Also adding a buss bar would be a good idea.

Thank you so much it helps me understand so much more how my boat works.

excellent video. the best and clearest explanation I have found. thank you very much for sharing

Přesně tohle jsem chtěl vidět. Super video! Děkuji

Good video work for a basic wiring layout! For my bilge pump and float, I chose to "parallel" ( instead of being in "series" like your schematic) the float switch to the pump and it has it's own direct to battery ( but fused) +12V connection, and, instead of that bilge pump power going direct to the fuse panel, my boat's original wiring has it switched at the helm, so I kept that function and can operate it manually or let the float turn it on when needed. I also have a 10 Amp charger/ maintainer ( Minn Kota brand- absolutely fantastic charger) connected direct to the battery with its inline fuses, then, everything else is on a master disconnect to a Blue Sea 150A panel. This way, when I am docked and I can get 115VAC shore power, I can shut off the main disconnect, BUT, my charger is connected to the battery, and the bilge pump will do its own thing, without needing the main disconnect ( which is hidden in a locking access panel) to be left on. This will insure that the bilge pump will work and the battery charger will replenish any charge when it is operating as well, and any ignition and accessory function is killed to prevent any "hot wiring" attempts.

the best explanation of electricity for boat congratulations the best

Thank you! Just inherited a boat that dad had been rewiring, still working in getting my license.

Thanks so much for your tutorial!

Great content, very simply explained, thank you

This is a great series thank you, subscribed

this was very helpful, thank you.

Dude... Your my hero!

Exactly what I needed great video

Wow. I’ve watched many seminars and videos and this was very clear. I will look and see if you did any videos on fusing from the battery. I understand a double pole is needed for this system. Thanks!

Thank you very nice diagram .

Good job, so helpfull Thanks a lot

It was a great video. thank you

Very good information Joe. Iv been working on my 2018 Triton SF18 Bass/Ski Boat for a month now. I Have two Helix 12 ,minkota Ultrex, trolling motor with its own battery source and decided to add Humminbird mega Live and mega 360. Iv added a Helix 10 for the down imaging . Both units require their own on and off switches and fuses. All went well until I add a ( Y ) cable to have the ability to monitor both down imaging and 🪧 on the same unit. Also, I have an ethernet hub from Hummingbird, connecting all graphs. I have a separate power source a 30 amp milliamp Lipo battery connected to the ( Y )cable , and realized that I had two different power sources entering the same unit. And my boat shorted out . Where should I start the Diagnosis ? To locate the short. I have a Honda 170 HP engine lost power to the tilt . Both circuit breakers did not trip. All batteries checked out fine. any suggestions where I should start to diagnose?

really good info. thanks

That was amazing, love the strep by step. How about a diagram when adding 24 volt electric motor, then add a battery charger to the mix and also how to charge both the 24 v battery to the motor's alternator? Too much? Thanks in advance

That was awesome. Answered a lot of questions. Maybe you could make a list of the gadgets wire needed for each application. Thank you

Best part…..Freaking Honda Hubcaps on the trailer, that’s ingenious ghettofication!

Great vidio mate thanks

Hi, great video! Thank you! I bought a fuse box but i’m not sure about what fuse to put for my fishfinder etc. Also what kind of AWG cables do you use for the different connections? 🙏🏽

Nice diagram Thx

Wow, very simple but instructive video, it gave me an idea about how a boat is wired. One question, the green wire that comes from the gages to the box, what are those for? Why they must be connected in parallel?

Perfect..thanks

I linked to your video in my video!

I'm wondering where you get the graphics for the different system components you have in your diagram - are there online libraries for these, or do you just scavenge them from websites and catalogs and resize to fit? Many thanks!

Thank you for sharing this. I was wondering what do when you have a steel boat. Steel hull. Should I connect the negative to the hull? Thanks

Good video brother

Great explanation and break down! Any chance of seeing one for an inboard motor? Been looking all over south Florida and no mechanic wants to work on an inboard. . . . I am specifically looking for a closer breakdown of the key ignition with battery, starter, ignition and accessory. Does it connect to the throttle?

Thanks Joe

You should add a power on/off switch for both.

Thank you.

If you’re running a switch panel, do you run two wires to the fuse box? In other words, one wire from electric component to the fuse box, then another wire from fuse box to switch panel? For example, if you wanna run a light switch? Or bait pump on a switch?

Hi, one of my gauges (water pressure) does not illuminate, does it have a bulb of some kind? It is a new boat. Is there a particular color wire that controls the light? All my other gauges illuminate. Thanks

Sir please help on this scenario. I have two power wires/ different circuits at bow of boat. There going to an sw but, I need to install a 1&2 amp fuse inline of each and install back to sw as one wire?. Since there is no fuse buss at bow of boat. After installing these fuses can i run straight to sufficient ga power wire at bow? Thanks JP

Excellent Video I really like your explanation sir. Sir could you show a video of a wiring connection of a tachometer on a Merc 150 blk max mtr? My tach lights up when I turn on the ign. but does`t give the RPM signal .

Wow! What a great video. My problem...I bought an SX210 with no battery in it. Wires all over the place, red black and other. Connected all the red to pos and black to neg and blew something....how in the heck am I going to figure out which is pos and which is neg on unmarked wires at the batter box? Going Crazy. Tks

Just one question: My ignition switch has a ground (black wire) should I connect that to the 'with IGN' ground ...a little confused. I tested the ign wire and it works gauges without that separate "with IGN" fuse bar. Thanks!

Hi, would you fit a circuit breaker between battery and engine? Also between battery and always on fuse box and battery supply to ignition?

👍

I wired my whole boat 1 12volt battery just like this, my question is, is it safe for a Terrova trolling motor to be plugged in while the 25hp motor is running and slowly charging the battery from the rectifier, I hear a lot of bad stories of circuit boards frying on Mini Kota's newer digital trolling motors mainly due to using 110 volt charger while trolling motor is plugged in.

😊😊😊

Thanks u si much

Joe I want to put a new fuse block in my boat. The wires running from block to bilge pump, radio, lights will be 14 ga tinned. The power feed to block from battery should be what gauge? or is it ok to run 14 gauge?

Great video man 👍🏽, I’m having a problem , man gauges work when the ignition switch is on but once I start the engine all of them stop working , any idea ?

Very nice diagram; where can find how to connect the outboard wires to controller for Handa 35 hp

I’m restoring a 2000 model skeeter zx 195c bass boat with all new gauges and sierra rotoswitches. Problem is I cut out all the old before researching the wiring schematic availability which is zero. I can’t find anything. Now I’m trying to figure out how in the world to hook all this back up blind. I’ve always been able to use a schematic. Stupid me I know. Lesson learned the hard way. Any suggestions on diagrams for these style switches and of course the gauges. Running Fuel,tilt/trim,rpm,mph,voltage,and water pressure gaugs.

Should be a complete disconnect on the +12V at the battery.

Thanks

Hi Joe! Could you combine this video with the battery switch video? At the end that is the most common installation. Thanks in advance!

Would you be so kind as to show a diagram of wiring a fly bridge . Joining both the upper and lower Helms. Nav lights, 2 Bilge pumps, 2 Maserators, Live well, shower, Transom pump, water pump, blower, cabin lights, VHF radio, stereo, Horn, house battery, starter battery, Thx you your videos are great.....

I’m just curious if you were to throw a kill switch in where would it go?

Thank

So my project boat has a switch box (that’s what google says it is). Can I remove that if I’m putting in a fuse box?

Why is the boat's engine wired directly to the battery and not to the fuse box powered by the ignition switch? Seems like it would make sense to have the engine powered by the switch than directly wired to the battery.

Hello Joe, my speedometer needle is not working, and I noticed when I advanced the throttle, it is the needle of the fuel gauge that is moving towards "F", instead of the speedometer needle.what is wrong with the wiring? Thank you!

Would Would this be similar to a outboard motor set up

What about wiring a trim gauge.I have a mariner 60 efi 2024 four stroke and bought the gauge but not sure how to wire up Can you help with this Regards Andy

Is the always on and with ign boxes fused at each connector

can you charge both batteries at the same time with a portable charger?

Hi boss can you tell me how I install battery cables from motor to batteries please please

Why do my boat gauges peg and alarm sounds when I turn nav/anchor on

I am sure that if you put a fuse in your fuseboxes , fuses are all blown. You need to have a negative eart-busbar to connect all negative lines. And someone asked about using boathull as negative line, as in cars. That's not a good idea, it causes corrosion in the hull.

People are asking because there isn’t a lot of good detailed examples of writing. I’m writing this before watching your video but I can tell you I’ve been looking and have not luck. Most are not detailed enough. Many are not professional quality or they are trying to sell the equipment.

What is the gauge/AWG size of the wire from the battery to the ignition switch?

Shouldn't they be a main battery switch

Bro what you can make a video on kia. Cooling mudule

I need help connecting a killswitch to my boat please

how you do ground

I don't think your ignition wire is designed to power accessories. You're supposed to use a relay or solenoid.

SAY IT WITH ME GAYYYYYYYYYGE NOT GOOOOOOOGE......... GAYYYYYYYYGE = GAUGE..........
