Well, the 55 Fleetwin did not have a lower cowl, so the water would have been dumping right out of the cylinder head under the engine cover. Was water dumping out of the bottom of the head or not? Don’t really understand what you meant by "coming from the stem". Perhaps you can point it out in one of your pictures. I tried to find the part numbers of these core plugs but the 1955 stuff seems no longer online at marineengine.com.
Do you see the bottom of the cylinder head where the core plug should be in your top picture?
Please be sure to order a new OEM impeller along with lower seal parts along with the two core plugs, the gearcase is easily removed now that the powerhead is off.
