That is just some oil that drips down the exhaust pipe after the motor was winterized which injects extra oil into the motor to prevent rust and corrosion. When you ran it on a hose, the motor was not run hard enough to burn off the excess so some of it came out with the exhaust.
No problem. When you take it out on the water and the whole engine warms up under load, the excess oil will be consumed.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor.

The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
