I have a merc 9.9, and plan on changing the impeller. Prior to beginning disassembly, the manual says to place the outboard into forward gear. When reading about the re-installation, it doesn't make sense to me. It says:<br />1- place shift linkage on engine in forward gear position.<br />2- tilt engine to full up position.<br />3- Place gear housing in neutral. Propeller will rotate freely in either direction when gear housing is in neutral.<br /><br />How do I do both #'s 1 and 2? I guess what I am asking is, how do I know that the shift linkage is in forward gear position, and how do you place the gear housing in neutral?
