Today I began awakening a 1986 Evinrude 140 E140TLCD that has not been run in at least 14 years. I originally posted about this way back in 2002, but got completely side tracked with a new son. So here we are 13 years later!! I am totally new to outboard motor repair, or any motor repair for that matter, but want to give this a try. I have been reading numerous posts about what needs to be done. I have a service manual, and am hoping this engine will turn out ok.
I pulled the lower unit to replace the impeller today. When I drained the gear lube, it was pretty black and smelled burned, but I did not find any metal shavings on the magnet. It was not milky at all. So appears that there may have been overheating issues. I removed the water pump, and the impeller was curved but intact. However there was a lot of pitting on the drive shaft where the impeller sits. Don't know how this happened. Inside of impeller looked smooth. The rest of the drive shaft above the impeller was fine. A little very light rust. Splines look good. Will this require a new drive shaft? Pretty worried about this.
Also when I rotate the propeller, there is a click in the gear case. It happens when I turn it either way, is that normal?
I removed the spark plugs and squirted some oil into each cylinder. The flywheel rotates without any appreciable resistance. So I guess the pistons are not stuck. Next two things I plan on doing are checking the spark and compression test. Can these be done without the lower unit attached? Or do I need to wait until I get the lower unit put back together?
Thanks for the help!!
