T&T: Welding cable

    Gil,
    One of my winter projects was to replace the 20 year old welding cables
    used on my starboard engine with 2/0 battery cable. The insulation had
    started to separate from the the wire on the ends and there was chafing on
    one area. I replaced the cable from the starter to the battery switch and
    back to the batteries and the cables connecting the two 8D's starter
    batteries. One of the side effects of the project is that the starter seems
    to have twice the juice as before. I never had a problem starting the
    engine but now the engine turns over much faster and starts quicker.
    Obliviously the old welding cable was not conducting as much juice as the
    2/0 cable.

    I was also shocked by the high price of Ancor cable at the local WM so I
    looked around the web and bought the cable thru bestboatwire.com. The wire
    is Pacer Marine and it's spec's are identical to Ancor but it's price is
    much less, 3.42/ft at bestboatwire vs. 7.49/ft for 2/0 at WM for Ancor
    brand. It's amazing how many feet of cable are required to go from the
    starter, around the engine, up to the on/off switch and back to the
    batteries. Add in the cable lugs and shrink tubing and you've spent a lot
    of $ but it's a project worth doing. Next winter I'll replace the cables to
    the port engine.

    Usual disclaimers, just a happy customer.

    While at my local boating supply store (a national chain) I was picking up
    some 2/0 marine cable; it sure is expensive. An employee of the store said I
    should go to the local welding supply store where the same gage welding cable
    sells for 25% of marine cable. Should I take his advise? If not, why not?
