I have a 1971 55HP Chrysler. On the starboard side of the LU. There is a little hole. Just above propeller but on starboard side. While engine is running a whitish grey milky oil with bubbles is coming out of this hole. Is this normal?
There is a little hole on the starboard side that releases water on my 70hp, but milky oil isn't one of them.
Have you inspected the condiition of your lower unit gear oil? If that is milky or has water in it, time for a new seal kit. I just did one on my 2 weeks ago, what an enormous difference. Nice not to have oil dripping from my LU while parked in the driveway.
Noah put a little on your finger and smell it. Does it smell like gasoline or lower unit oil? My guess is it is unburned gas oil mix draining into the motor leg. This can be common. Unfortunately Chryslers are not environmentally friendly. I doubt yours has a recirculation system for the fuel. Look on the port side. Is there a hose going from the bottom of both cylinders then it goes to a Tee then connects to the Kingpin? Here is what was explained to me on early model chryslers. During idle and even at higher speed gasoline will condense and drain to the bottom of the cylinders. In order to produce a better idle this gas needs to be removed. Newer models will have it reciruilated and re burned but older chryslers dump this into the lake. This might be what you are seeing. If you do have a reciruilation system you may need to clean it or decarb your motor. If you travel with the motor tilted up this will a lot of times cause the fuel to drain because the carb needle valve has trouble staying closed when the motor is trimmed.
