Hey gang ..I’ve got a leak presumably from somewhere in the raw water cooling side, but I can’t seem to reproduce it at the dock. It seems to be coming from down low somewhere, and has been going in long enough that it’s badly rusted the exterior underside of my starboard inside manifold. At the dock, I run the engines and rev them up to about 3000rpm, but there is no water spray. I had cleaned this up and tightened some hoses and painted the manifold, but after having it out today for an hour, the underside of that manifold is white with salt. Leads me to believe that this is only happening when the boat is in gear. Could it be related to a shaft seal? Why is there no water spray while at the dock in neutral? Any ideas?
