Have what I believe to be 19 ft 1970 lonestar. Looks like a sylvan. The former owner must have rewired it years ago but didnt do a great job. I want to redo it and make sure its done correctly. Wich means I have to start from scratch and since I am not a marine wiring expert I need to find out the correct evrything to use and do. ex, I want to know what switches to use, type of fuses and blocks, guage wire, what accessory to wich switch? I found a color code chart already. I found some books for sale here but would like a little help choosing the path to this knowledge. Something downloadable or a website would be awesome! I have the ability to just copy whats there but thats not good enough. I want it safe and correct so Im going the extra mile here. Thanks for any help. Glen

Re: complete rewire

Very few electrical items are made specifically for recreational boats. Almost all of it has some other use in some other industry, and is often less expensive if purchased from an industrial supply source. In a nutshell, a boat is wired with items that are spec’d at NEMA 4, or preferably 4X. That is the std for electrical goodies installed in a corrosive environment. Switches, electrical boxes, wire, terminal blocks, connectors, all of it is designed for use in a corrosive area and thus works well on boats.<br /><br />I think the folks here can offer you some good idea and tips but I think a book is a good way to get started, and it has handy charts you will be referencing often. ‘Powerboaters Guide To Electrical’ by Ed Sherman is a good place to start. You can buy/order it here from iboats’ MegaMall.<br /><br />- Plan everything before you start the actual rewiring. First do a basic plan, then a detailed plan. Keep it simple.<br />- Wire nuts will not be used anywhere for anything on your boat.<br />- No aluminum conductors will be used for anywhere for anything on your boat.<br />- Wire with a single, solid conductor will not be used anywhere for anything on your boat.<br />- Label all wire, both ends, and if you have a bundle also label somewhere in the middle where it can be seen if needed.<br />- Colored wires are pretty but not necessary, except for AC. It will be significantly less expensive to purchase a single, big spool of black wire for everything and used colored shrink tubing and labels to identify the wires.<br />- Decide on if you are going to use a single crimp or double crimp connectors. Single crimp seems to be favored by many folks that also solder the connection, double crimp offers some stain relief where the wire and connector come together.<br /><br />That should help get you started.<br /> :)

Re: complete rewire

One additional item would be ready made switch panels. Here on iBoats.com as well as other on-line stores, you can buy ready made switch/breaker panels just like those used on newer boats. These panels have the switches and push button circuit breakers right on the panel so there is no need for a separate fuse panel. If you decide to use a fuse panel, use the type that takes the blade style fuses. They are smaller and far more convenient.

Re: complete rewire

I have just rewired my first boat from scratch and it´s not difficult at all. I just did some searches on this forum and pretty much followed the guidelines the guys above have stated. I did not think it was neccessary to color code all wires, so as a compromise I bought good size rolls of black and read marine wire, 10 & 16 gauge - at least you will always know your hot wire from ground - and then just labelled the heck out of everything to make it easier when I will need to disconnect something.<br />Don´t know what gauges you have on your boat, but this is a good time to add some - I´d regard both water pressure gauge and cylinder head temp gauge as essential to see what´s going on in the engine room. Good luck.

Re: complete rewire

You can't do the right job, the right way without the right tools. Many members will recommend a ratchet style crimper. Search the forums and you will find sources and pictures. Also if you have a PartPlus/AutoValue parts store nearby pick up a tool sale flyer from ATD "Simply the Best" they have ratchet crimpers in there for reasonable prices.<br /><br />As for wire, check out Waytek<br /><br /> Waytek Wire <br /><br />It may be mail order, but they have just about everything you will need, if you can order from them. I don't know if you will need a sales tax license or not, but they are not hard to secure either. NAPA stores are able to source marine grade wire too.<br /><br />Good luck, you seem started in the right direction for doing the job the right way.

Re: complete rewire

I found an Ancor wire crimper that did not say ancor but was half the price.<br /><br />I can only say that it can be found with all sorts of other stuff on an auction site.
