Possibly Right Here at iboats.com's Marine Mega Mall,..........<br />It's the little Blue link at the Top of this page........<br />And,.... There's Always ebay......
For those that don't know, those are the one piece exhaust manifolds on some of the V6 Mercruiser engines.<br />
<br /><br />I don't know if there are aftermarket manifolds or not for replacement, but you might try going to Mercruisers Parts Express with your engine serial number and see what's available.<br />I just looked at the Merc parts catalog and they are about $623 USD per manifold. At dougrussell.com, they are $1100 USD each
O,......Those Manifolds,................. <br /><br />I'd convert it to the 2 pc. style,..........<br /><br />Seems like I saw a "Kit" Somewhere,...... NAPA,.. Sierra,... OSCO,...?????????
I am also in need of these manifolds. I tried Sierra, Osco, Barr, etc. but could not find anything. Merc Express Parts say they are no longer available. Any help will be appreciated.
Keep an eye on ebay. I see them for very reasonable from time to time. I have them on my boat and almost want to pick up a pair just to have a spare set.
