it seems more like i have reversion problem. you can see where the elbow is even wet after running the boat for about 20 mins. I replaced the riser gaskets and sealed them real good with head gasket sealer and let it set over nite, still water in the oil. I am going to weld 6" x 3" stainless stell to the exhaust port on the riser so that the water and exhaust gasses do not mix so close to the elbow of the riser.
If they are GLM manifolds they could have likely been flawed from the start....You would be shocked if you saw what I have pulled out of the box new from them

Ken, EMI Thunder's would be a much better choice. They also have individual runners which is what you want. You won't regret it. Just my opinion. Obviously you have numerous different routes you could go so just do a little research before you buy just to make sure you get the best bang for the buck however I think your on the right track.
