Thread: Tinnie corrosion?

  1. #1

    Tinnie corrosion?

    Hi all, this is the 2nd time I've had this problem. I have a homemade live bait tank and I THINK it may have a leak as there appears to be crusty salt deposit see pic emanating from that area. It is very hard and I have tried all the usual things, hot water, bringing it back a bit with a wire wheel on a drill then coating the area it in oil but it has returned.
    Any idea on why this is happening and how I can clean it and prevent it happening again?
    could it be I have the battery cables on the battery and its reacting to a slow drip from the bait tank or.....

    any help would be appreciated
    cheers

    I am wondering if it could be calcium buildup from the water. I get it sometimes on my reef aquarium. Best way to remove it is something acidic, and on the fish tank glass I just use vinegar. Maybe start with that and only try slightly stronger acid if needed.

    If that is what it is, then yes, you must have a leak from the bait tank.

    Hard to tell from the pictures is it pitting?

    Does the tank normally sit in front of the build up?

    Re: Tinnie corrosion?

    if the battery has exposed terminals and getting wet it can earth through the salt crystals to the hull

    I think what you are referring to marto is the platform that the floor is screwed onto, or the paddle handle...

    Mitc, I've wire-brushed it on the end of the drill and tried a few other ways, then put a smear of oil to protect it or stop it from recurring but....and what would u paint it with?

    Bay fisher I don't think its pitting as I've ground it off once before and the metal looks ok once you get into it, it's a crusty sort of thing, harder than I would've thought tho

    Gazza, I don't think I do. The only wires that I had were connected to the battery from the motor charge unit and the electric start. I don't have the motor any longer as I've just sold it. I also have a fuse box attached to the hull with cabin lights, sounder, Nav lights etc installed by someone that knew what they were doing (not me lol)

    Re: Tinnie corrosion?

    Yep it does and I thought after I'd scrubbed it back last time that I'd selastic around the inlet/outlets n see what happens then, then.....it's the ONLY place it's happening so I'm guessing that it IS the live well and maybe there's a current coming from somewhere as well. I dunno...ANY ideas on whether I can take the boat somewhere for someone to have a look?
