I have a mercury 1981 50hp 4 cylinder 2 cycle outboard.I pulled the lower unit because no water was coming out of the phole when I pulled the unit I notciced a tapered gromet had fallen out .the gromet has splines on the smallest end and appears to go on the end of the drive shaft at the top.It has 9 notches and matches the drive shaft it appears.Anybody know for sure if that is where it goes? Also I had a BRAIN FART and accidentally had the gear in reverse rather than forard when I pulled the lower unit,what can I say I'm getting old,anybody that can help will be greatly appreciated....Thanks
