    Default New boat Zinc Wear ?

    Is this typical wear on a boat with 13 hours on the main engine, 4 hours on the kicker, 2 days sitting in the water with minimal power on when on anchor?

    looks like its eaten up more than i'd like to see for such a short time in the water. Hope you don't have the makings of a giant battery there.

    That is exactly what I am thinking. I sent pix to hewes to see what they have to say.

    Wow. Guess I should sink my pos then. My hull loves to eat zincs. All my wiring is clean and newish. Guess I better start checking things out now

    I looked through the wiring pretty closely when I put the new transducer in. It all looks clean and tight and well installed. Maybe this is totally normal. I wouldn't sink her yet Rob!

    I am re-thinking that I just have a case of the new boat jitters.....

    I'm no expert on boat bonding but if you guys are eating up those zincs for the short times you are in the water i think there is something wrong. I had one that size on my bowpicker and i only changed it every 3 or so years and that boat was in the water from may till september. It might be different with tin boats but i've never heard any of my buddies with them complain of zincs eating up quickly.

    Looking at the zinc I would be surprise if you don't have a problem. That zinc looked like it lost a lot of metal in a very short time. Did you get a wiring diagram for the boat it would help find a problem if you have one?

    Check to see if you have a negative ground post, and not using the hull for the negative for all the lights and equipment. I ran all my grounds to a post and directly to the battery. I left my 34 footer in the water for 4 months and had less than that for electrolysis corrosion. Do you ever plug into shore power, that can cause a lot of problems also. Good Luck.

    That doesn't look right at all. I have a new Hewes also, with about 10 days total in the water and my zincs dont have any pitting whatsoever. Something is crossed up somewhere.

    How new is your hewes and what model?

    They told me to keep an eye on it and take it out again - if it gets worse they are going to look at it. Sounds like Hewes might be using different zincs - BUT I bet they don't change out the Yamaha zinc on the lower mounting bracket and it is pitted also.

    Gman - No shore power. The fist post explains the situation. I was anchored in Cathead Bay and Bettles bay for 2 nights out in PWS.

    If by sitting in the water you mean the Seward boat harbor that place will eat them up in a hurry.

    .
    At first I also thought the same thing, some how they put the wrong type of anode on the hull. Until I determine it was a zinc anode. What ever the problem is, it's not the anodes.

    Hey Bullelk, I take it back. I just went out and checked mine closer, and they look exactly like yours...just didn't notice it before. Either we both have a similar problem...or they're simply working as advertised??

    Bullelkklr, just finish talking with an expert on corrosion problems and confirm my suspicion. But first I need to know how much the mini divers dream and the hand bar zincs weights. Can you remove and weigh them for me. I need the information to prove or disprove my suspicion.
