I have a 1979 Cobalt with a Mercruiser 260 in it. My port exhaust manifold (part no 77234A7) has a crack in it and is leaking water. I am looking to order the parts to replace it and needed some advice. I think I will be getting this part from mallory ( Mercruiser Port Manifold V8 77234B , 77234A7, 77234A2 ) and had a few questions.
1) Can I reuse the existing end plates (OEM as far as I can tell) or do I need/should to get new ones?
2) This picture ( http://www.mercruiserparts.com/Show...r=60&bdesc=EXHAUST+MANIFOLD+AND+EXHAUST+ELBOW ) shows two plugs. Again, can I reuse the existing or are new ones required?
3) As far as gaskets go I know I need new gasket sets for the end plates, riser and where it mounts to the engine. Did I miss anything?

Thanks in advance for the help!

Re: Exhaust leak help

Check the condition of your end plates, you may want a new ones. It may not be an easy job to remove your old plugs so I'd rather go with all brand new stuff.

No doubt!! The parts are expensive enough! Thank God I can do this stuff myself. Of course it is an old boat so it's not as fancy as the new ones but it floats! :)
