    Can anyone tell me what the anodes on a motor (gas or electric)
    are for. I have an electric MinnKota that has them and I am looking 
    at a Yamaha outboard, which the literature says has anodes. Are you 
    suppose to replace them. How do you know when?
            
    Thanks

    The anodes are of a sacrifical nature. They are installed to prevent
    crosion (sp) of your outboard. They are more subceptable to
    electrolysis than the Alum. or Bronze. You will know when to replace
    them when you noticed that they have corroded to the point that
    they are about to fall off.
    
    On an out board, like your Yamaha the skeg anode also serves as
    a tourqe stablizer and you will notice pulling in the steering as
    it wears away. Adjust new skeg anodes very slightly in the direction
    of the pull. ie: pulls starbord adjust to starbord in small 1 deg
    increments.
    
    You also have anodes on the tilt assy which should last longer as
    they are larger.
    
    Do not paint the anodes as they will not do there job. 
    
                                good luck

|     IF YOUR RUNNING IN SALT WATER THEY MAY HAVE TO BE REPLACED ONCE
    A YEAR. BUT THERE CHEAP TO REPLACE AND CAN BE A BITCH TO GET OFF!!

|     replacing an anode is a judgement call. they may look ok, but they
    may have already given up the sacrificial materials and still look
    good. if your in saltwater a lot, it may be best to change them each
    season. if you do most of your boating is fresh water, i doubt
    you'll see much wear, unless your running a boat with a battery
    in it, then possibly you may see some degradation.
    
    happy zincing,
