I have a 15HP Evinrude that was passed down to me and I've been trying to get it running again. It looks like it was taken care of by the previous owner, but it hasn't been used in years.
I finally got it to start after replacing the impeller, plugs, fuel lines, and cleaning the carb, but it will not shift into forward or reverse. I checked the usual suspects like the rev limiter, and the linkage connections, but I think the problem may be in the lower unit. It feels like the lower link rod is stuck.
I also changed the oil in the lower unit and it was black with no signs of milky coloring or metal shavings. Any suggestions on what I can do?
