Re: 1977 120/140 MerCruiser Upper/Lower Unit Parts Needed...
Took drive shaft housing cover off, found water which I know isn't supposed to be in there and a piece of metal between two teeth on the tapered gear on the shaft that comes from the engine. How do I turn the shaft around so I can inspect the rest of it? I have the shifter in forward gear, it clicks when I rotate the prop.
