I have a 1999 Bayliner 5.0 with a Bravo 1, gen. 2 sterndrive with only 50 hours on it. I just bought it from my late brothers estate and there were no records kept so to be safe, I replaced the impeller. The boat was kept in the garage and looks like new but looks can be deceiving because I've already had to rebuild the carburetor because of ethanol. The book says to spin the prop clockwise to spin the shaft when putting back together so the splines line up but when I spin the prop, the shaft doesn't move. The shifter lever is facing forward and when I spin the prop the shift lever clicks to the left and then faces forward again and the shaft doesn't move. Am I doing something wrong? As you can tell, I'm new to inboard outboards. Thanks for the help. Scott
