I am exhausted searching for both exhaust manifolds for my OMC Cobra 4.3L. Have done the soddering job once - don't want to push that - really feel it's time to replace. Anybody know where these can be located? Preferably used.<br />Thanks!

ClearLakeJohn,<br />(yeah,you did pick an exhausting subject,grin)<br />Last I knew,DougRussellMarine had them,but the price was very high,I heard this word of mouth.<br /><br />I was at a dealer meeting last November in Conn.and talked with an Osco rep.He had a way of doing this,with new parts,and it did involve some cutting.He also said Osco was working with a solution,and it may be out by now.Try KelloggMarine.Com.It was their dealer meeting I attended.They did it up very well,as they do every year.<br />Good Luck<br /><br />DHP

www.dougrussell.com had some when I checked a couple of months ago, but they are really pricey!<br />I heard that GLM is coming out with their aftermarket version of the one piece OMC manifold, but I can't tell what the quality is.<br />I replaced my OE ones last year, and I have a spare set for the future (salt water area).
