    Contact Engine Nut on this forum. He works for Indmar.

    Not anymore, it was about 7years ago. MC of AZ put me in touch with them (and they helped as well. Probably not going to get much help from S&W unless things are different than when I lived in CO).
    SOmeone will have contact info, or just phone up Vonore, TN and ask who you need to talk to about this.

    Thanks, I will do that. Do you have any points of contact back there you could share? Thanks for your help and advice!

    I would talk to someone at Indmar. They are a pretty good company and I think if you politely but firmly explain the situation, I would think that they would come through for you.....................especially because there is a recall on the manifolds...
    I have only had good service and interactions with them.

    I had good luck witha defective part by approaching MC/Indmar directy. They are not in the business of gving away parts, but in my experience they are in the business of maintaining their reputation for producing a quality product.
    Otherwise, I'd go with CantRepeat's suggestion (are the manifolds cast iron or Al?) drill out the leaks and put a short brass or stainless screw in the holes. Should be a permanent fix, cheap too.
    I agree with your statement of MC standing behind one of their longest TT members and helping him get a new set of manifolds. We do have a few phone calls into MC to see if we cant get a solution that way. For now so we can stay on the water we chose the JB weld route and we shall see if that work. S&W probably isnt going to help...direct to MC is our only hope.

    I could be wrong but yours looks like a plug possibly was there, as it appears there is a decent size hole. Was there a plug or is it just the way picture looks?
    It looks like the hole size varies due to the amount of corrosion on the inside. The outer weld diameter is the same about 1-1 1/2" diameter. We groud off the black power coat and then cleaned up the visable outer corrosion then applied the JB weld and that has worked the best with no more leaks...yet...

    I had the same issue. A buddy of mine owns a garage and just removed and then welded in new plugs he fabed up.
    Now I did hear recently that Indmar knows of the issue and if you push them they will send you a new manifold no charge....Not 100% on that though....

    wont that cause a reaction and eventually corrosion? brass on alum?

    Either way you'd probably get more than 4 yrs out of the brass plug haha

    Yes that is water coming out. Yes they are powdercoated black. It is a LY6 6.0L Indmar Motor, 2007
    Is it just one side?

    Looks like the best fix is to pull the manifold, grind off the powder coat, spool gun some aluminum in there and either put them back on or get it repowder coated. I'd probably just polish up the weld.

    You might also be able to drill and tap the holes and add a brass screw in plug.

    The boat is my father inlaws who was a TT memeber since 1969 and decided to retre with his 2007 boat. He takes VERY good care of all his boats and this one is wiped clean every time it hits the water and then returned to the lift. The boat has under 500 hours too. It looks like they are welded shut and about 1/8 thick at most.
