Have to rewire an 18' Sylvan. I seen some helpful diagrams. I'd like to learn more about marine wiring in general. I'm an auto mechanic so I'm thinking theres some manuals for education purposes or websites with course material etc. But before I look further on my own I'd appreciate guidance from the experienced people here as I feel the information I've seen here is very reliable. Thank you

Marine grade wiring is special, and not used everywhere it should be, likely because of cost. It is tinned, stranded, wiring, but the strands are thinner and more numerous for a given gauge wire, versus non-marine grade wire. The insulation is likely heavier as well.

The tinned strands allow easier soldering, even after exposure to marine weather conditions. Still, you need to use a heavy soldering iron and plenty of flux, to solder older wiring.

Use marine grade (tin coated wire) to prevent the dreaded “black wire disease.

As with all wiring applications subject to vibration, connections are crimped. No soldering.

Hint....buy a decent pair of crimpers. Nothing worst that trying to make good crimps with cheap crimpers.

Use marine grade (sealed) lugs and or adhesive lined shrink wrap.

Service loops (excess length) are your long term friend

Thanks , I remember grandpa and my uncle teaching me about service loops many years ago, wish I asked more, navy men.
