A friend has a boat with the mercruiser 4.3 one piece exhaust manifolds that are leaking. Looking for options since they are no longer available from Merc.

Pretty much all he can do is replace with 2 piece setup. Next post will have a link to a page with the relevant service bulletin - click on the service bulletin link near the bottom
We have the kits in stock. In addition to the kit the manifolds and other pieces need to be ordered separately.
