You should be able to drop the unit down and remove the hose without draining the lower unit. this should be an enclosed cavity and no oil should be present. If you have ever reemoved your lower unit before it should drop down fairly easy. i usually keep a floor jack under the skeg to lower and raise the unit into place. Just be easy and don,t force anything. Remember that the shift rod is in there too and will have to be lined up before the unit will slide back up. A second person is a great help in doing this also. Once the unit is lowered the speedometer line should either pull right off or may have the pinch type hose clamps on it. Good Luck.
