corrosion in exhaust
 

has anyone ever had a problem with corrosion in their heades from slat water running? we have three sets of cmi headers for bbc, and we sent one off to cmi because it had a crack in it, and they claimed that is had corrosion in the header or something like that because of salt water, is it possible to "clean" it out? can you run them like that? we dont really want to spend 8 grand for new exhaust :( thanks

have seen it many many times, you can flush them with saltx or simmilar product would also recomend press testing them to be shure of no leaks, and would recomend flushing the mtrs after each use

we dont run in salt ever, its just that we bought the boat as a project that had sunk and hadn't ran in over a year, so are not sure at all of its history. since all the headers are off the boat, you mean we could clean them with saltx and that would clean them out so they would be useable? thanks

i just put stellings headers on so i have been trying to sell two sets of the stock mercruiser/gill manifolds cheap if your interested pm me. didn`t mean to make a classified

thanks, but if we need to buy a new header we would go on and get a cmi to match.

i sold two sets of cmi sweptbacks on ebay last year off my 525`s they went for 1500 a set freshwater. hopfully thats a good gauge for used value.

HOW MUCH FOR ONE SET I MAY BE INTERESTED.

the pastowner of the boat claimed these were cmis.....just want to make sure if they are, because, they dont look like any new cmi model...they almost look more like a hardin marine type..

i would like to see 3000 for the two sets but i`ll split them for 1500 a set let me know what you think. they dont do anyone any good sitting on the shelf
