Well, you should shop around: Sailnet, Genuinedealz and Gregs Marine. I'll bet Greg's will have better prices. I am not connected, just a customer.

1/BOTH/2/OFF Switches Thoughts & Musings -

Only difference for you with an outboard is that the negative for your boat is the battery (-) not the engine.

Good luck.
++1 on that

I am half way thru my rewiring project using the learnings I got here and from electrical handbooks from Charlie Wing (highly recommended) and Don Casey.
The trick? plan, plan, plan, do.

1) Draft a diagram based on Stu's links above.
2) Measure all the wire distances taking the wire runs up and downs around furniture into account.
2) Make a list of wire sizes (depends on the distances X 2) and colors
3) Shop around:
  • For wires
  • For connectors and heat-shrink
  • For a crimping tool (Pro's kit was the most cost effective for my project)
  • A good stripper and wire cutter
  • Bus bars
4) Buy
5) Get moving.

Best of luck
