On the Mercruiser Gen VI 496 MAG with closed loop cooling, there are four connectors (appear to be quick disconnect) fittings at the manifold on top, two on port and two on starboard (at the sea water and power steering pumps). Need to find out how to reconnect the air hoses. Are the connectors disposable? Since I never use the air-actuated drain system, can the boat be used with the air hoses disconnected?
Here are a couple of photos that might help illustrate my questions.The first pic is the top side of the seawater pump housing. The second is of the air system manifold located at the top front of the engine. The ring on the top of the white connectors are spring loaded. That tells me that they are some type of quick-connect fittings. However, when I insert the green or grey air hose, the fittings do not seem to grab and seal the hose. Any idea how these connectors/fittings work?
