" The lower unit on my 1990 15
" The lower unit on my 1990 15 HP Johnson finally gave up the ghost last week, so I went out and found a used gearcase off a parts engine. The guy I bought it from is a reputable mechanic and said the gearcase was in good condition, so I took it. When I got it home, it appeared to me that the driveshaft was in somewhat rough condition. I pulled that shaft out and inserted the one from my old unit. They are exactly the same and this one appears to be in better condition. I noticed that when I inserted the droveshaft, unlike on the old lower unit, I could not turn the shaft in such a way as to make the propshaft turn. I figured that maybe it wasn't engaging the propshaft, but when I put it on the boat, it would engage in reverse, but not in forward. In fact neutral also works, buit not forward. Did I get a unit with a bad forward gear? Is there some other explanation? Thanks for any help.
