    Thank you for the information guys. Can I test for leaks with this thing here.? I'm dreading the results. Getting the lower unit back on is a major hassle. T he shift linkage, water tube and drive shaft all have to be in the perfect spot or else it won't go back in place.

    Where do we buy manuals nowadays?

    It's been a while since I worked on a boat. I have an 18hp 1981 Mercury outboard that wont shift into drive or reverse. I don't want to go tearing into it without a manual. My question is, "Where are people buying repair manuals nowadays? Should I buy a paper copy or a digital one? It sounds...
