    Hey Guys,

    I need your help here again...For a fishing boat that's running a petrol outboard motor should I wire the boat using DC power or AC power??

    Cheers

    Sorry, can't answer that direct. Try Terry King on these forums. He seems to be the resident electrical man.
    Good luck!

    DC would be the most common , although if much power is needed hydraulics can be done with a belt or AC or DC power pony.

    What are you looking to power underway?

    A Pot Hauler or lights and radios?

    Hi,
    I suggest you wire for 12 V DC. This is the standard voltage used in small boats, so most boat equipment is made for this voltage. The 12 V technology in a boat is similar to the technology used in a car.

    There are safety problems related to high voltage AC (240 V), and dedicated boat equipment like pumps, lanterns etc. are not available for this voltage. There are a few things to consider when wiring for 12 V also, e.g. cable area and fuze sizes, but the safety issues with 240 V AC is of a different magnitude.

    Regards and good luck,
    Erik

    Sounds right...

    Erik seems right to me..

    You really need to detail what you're going to power, first...
