Well I just bought this boat. I am noticing that there is some discoleration like it got hot at the top of the riser elbow.
I have the Chrysler 383's does anyone know If I can do the risers with the boat in the water or do I need to pull it?
Since its all raw water cooling should I be changing the manifolds too? They are staying cool enough to touch probably just over 100 degrees. Engines arent over heating eithier.
This is my first inboard engine boat and boy do I have a steep learning curve. I am coming over from the StarCraft forum where I just restored an old 78 SS
