There are only 2 places water can get in, assuming the lower unit has no cracks. Thru the seals below the water pump and the seals on the prop shaft. Since you were hearing air coming out of the top, that sort of points to the water pump seals. If it is the water pump seals you should be able to tell using the muffs. If it were me, I would replace all of them. If one set has gone bad, there is a good chance the others might go soon. What kind of motor do you have?
I just realized I have been butting in on the Mo. board. I appologize for that. I just seen someone was having motor problems and try to help.
