I have an 83 bayliner with a aq125a and 270 drive. When i connect the muffs and water hose i dont see much water coming out of the exhaust. It barely sprays my hand when i put it in front of it. Is this normal? I heard people saying that it needs to come out the same amount that comes in, but how do i know how much water goes in if the muffs are splashing out most of the water. How much water should come out the exhaust when idle and with the muffs well placed? Also, should the heat exchange keep water inside the salt water side when not using the boat?
