Default Rewiring a boat?

The wiring on my boat is a total rats nest. I mean I get it my boat is 16 years old and I'm the 3rd owner. Has anyone in the Baton Rouge area just said screw it and paid someone to rewire everything on their boat. Just wondering how much it would cost to have it done. I'm fully capable of doing it, but seems like every minute of my life is pretty much accounted for until my he was date.😂 And it's hard enough to squeeze in time to take the boat out, and seems like stuff that needs to be addressed keeps piling up.

Best thing to do is start solicitating quotes. Have a FIRM idea of what it is you want done and have it specd out beforhand. A project like this can run away from you quicky if you don't have a plan.

Figure $60-$120 per hour plus cost of materials. If you are just doing primary wire and cleaning up the terminations, figure 20-60 hours of work. Add more if you re redoing engines and electronics. Custom switch panel? $$$$$. Again, this is contingent on your plan.

I spent a winter doing mine and probably put in 80 hours. It was a total strip and rewire, but I was happy with the results.

You’re looking at a minimum of 60 hours to just completely strip and rewire the entire boat from bow to stern. This does not include replacing other equipment and accessories. Our labor rate is $125 per hour.

I did the same as Popeyeiii, Stripped mine down over the winter and completely rewired it, line x'd the hard top frame, painted the hard top, upgraded the helm and stereo and called it a day. At the end, I have no idea how many hours a buddy and I put in, or how many beers were drank, but it was well worth it! I'd say start to finish I had the boat down for 2-3 months with all the work.

Front to back marine used to be an option in BR. I build my own rat's nests as I heard its not cheap. But would be curious what kind of quotes you wind up with.

Well at $7500 DWM is way out of my price range. Unless I win the lottery then it's ON! New electronics, twin 150's and a new truck, but I'd have to actually buy lottery tickets to win 😂.

Just got finished looking at your project you did great work. My batteries are under my console, so I was thinking about running one heavy ground wire back to the bilge and grounding everything to a bus bar similar to what you did. That way i'd only have hot wires running from the switches in the console back to the bilge pumps, power pole, jack plate, and wash down pump. Guess i'll have to add a rewire to the list and tackle it myself.

Expertise and efficiency aren’t cheap.

Not to be a richard, but that comment isn't helping your case. 😉. Guess I'm just a tight wad.

I was thinking of moving my batteries forward and running 1 or 1/0 to the motors, but the batteries have been back there for 15 years and never really had a problem other than they are a PITFA to get in an out. And I would rather have the console space. Been also thinking of a RHODAN so I would need that space for batteries.

That's what i'd do. Be sure to put the bus bar (or power post) high enough to be out of bilge splash and still be easily inspected and maintained.. I have used a blue sea terminal post ( power post plus) and tied both engine grounds to it and only one heavy ground ( like #1 or 1/0) wire to the console batteries. The "power post plus"has a good number of # 8 or 10 screw terminals for your equipment grounding. I just finished re-wiring a bay boat and materials were about 1100-1200 but that included wash down pump, 800 auto bilge, bait pump, and high water alarm switch., so, less than a grand for the wiring part. Now is good time to do it !
Oh, and DWM's hour estimate is about right, it probably took me longer than that but I am sure he would be faster, even much faster, since he has someone to help with some of the steps.

There was a guy in hammond or somewhere around there who opened a business doing this a year or two ago who was pretty reasonable if I remember correctly. I'll try to remember his name

No reason why you can't wire it yourself. Sure it may take you longer, a few youtube videos, of course some trial and error. At the end of the day you will not only know it was done correctly by your hands but also give you peace at mind knowing that if something electrical goes wrong you know where to look first. I had the same problem as you, tore out all the wiring and did it myself, the right way. Obviously as a aircraft mechanic I already knew what I was getting into but after hours of researching what I wanted and gather materials I was able to completely wire every system onboard and this was 3 years ago, haven't had a single problem. Well worth YOUR time and investment.

I rewired our bay boat (18ft Sea Chaser) last year. Took about 3 days, and maybe $200 in materials. I think I did a good job, used a Blue Seas fuse box and home-runned all the positives and negatives on the switches back to the fuse box. Looked neat, worked great! Then Sally destroyed the whole boat. Dammit. But the wiring was sound. The radio was playing until the battery died.
