Hey guys.
I have a carbed mecruiser 260 ( 5.7) and I have a bunch of stuff apart for upgrades and maintenence. One of the things I pulled are the exhaust elbows. The old gaskets were quite crusty and I can't tell if they were open closed or restricted. It kind of looks like they may have been closed and somebody hogged them out but I don't know for sure.
How do I determine which gaskets to replace them with and what are the benefits of having flow vs no flow through the exhaust elbows? I would think more flow = cooler and cooler is better.
I run coolant in the engine (using a heat exchanger) (I think you folks call it a closed a cooling system) and run it strictly in the summertime in freshwater in the Pacific Northwest.
Sorry about my lack of marine terminology. I'm a ticketed mechanic but I play with big dry land equipment most of the time.
