Snap Together Boat Wiring and Marine Electrical

[mitiempo]

I don't think it has enough flexibility. You never know how long a wire should be until you run it in the boat you're working on. Maybe for a small runabout or fishing boat. But I think there are too many variables for a larger boat. I think the plug in connectors could be a source of trouble as well. In a system wired in place there are no such connectors.

Those are really designed for much simpler boats than what most of us have. Also, trying to fish those connectors through the tight spaces on a sailboat would be almost impossible I was talking with Maine Sail this past weekend and he was having to coat wires with McLube Sailkote to get them through some of the wiring runs he had. We're talking individual 12 AWG wires... never mind anything with a modular connector.

You're also going to pay a price premium for those. Since they're pre-configured, it is really unlikely that you're going to get the right lengths you need or the right guage wire you need.

I think there made for power boats and most every 20' basic powerboat has the same wiring

The factory harness is made to plug into the motor and supply a connection from a 50 amp breaker to a sub-pannel at the helm and connect a full set of guages key start ect
