Hi guys, just fired up my freshly rebuilt 454 mag alpha only to find a hole in one of the exhaust manifolds(water jacket). This hole is visible when looking through the outlet with the riser removed.
I am hoping I have done no serious damage as the cylinders filled up with water pretty quickly.

My question is can I replace just one manifold with say a GLM or similar, or would I have to replace the pair to match as they were stock Mercruiser?

Thanks in advance.

if one just went the other not far behind I would bet !!!

Thanks for the offer but shipping would kill any deal we could do.

I have gone for some GLM replacements, are these any good?

I had been told GLM are slightly better than stock Merc because of longer dividers between runners. also, the are aluminum. I am not sure if the are coated or not.
