Well, I had to make a temporary plywood platform that would fit beside the engine that would hold my weight and allow me to lay down and wiggle my head and arms into the area of the leaking water hose/fitting. I was able to put a couple of turns on the hose clamp. Not sure if that "fixed" the leak, but I'll keep my eye on it. If this does not work, replacing the water hose is the only alternative, which will be very difficult to do. I almost got stuck in the laying down position, but I was able to get out. The hose clamp that I suspect was leaking is circled in RED in the photo.
