I have my 1985 140 hp Evinrude on the stand in my garage now just getting it ready for a paint job. I figured the smart move would be to replace the water pump impeller before I painted it. I bought the boat a year and a half ago and don't know the history of the impeller. Anyway The first step in my Clymer was to drain the gearcase. There was no oil there. Does the motor have to be in a certain position to drain the oil. If not, where could this oil have gone. There is no sign of a leak. I had it serviced about a year ago which was supposed to include and oil change. OH by the way, do any of you Guru's have some good impeller replacement directions or cautions, it's my first time. Sorry for the rambling post.<br /><br />Thanks,<br />Scott
