I have a 1983 Johnson 9.9, Model J10SELCTC, thats been sitting in storage for 15 years, and hasnt been serviced in over 20. I recently got it to run in a test tank and noticed that the water pump wasnt working. upon removing the bottom half i was greeted by an impeller with no dowel, and being 2 hours from my house had to improvise some sort of replacment that ended up working. but the gear linckage, that connects the gear stick thingy, was incredibly hard to reconnect. everytime i managed to kind of slip it into the hole, it would shift into the incorrect gear when i screwed the bottom half back on. it ended up breaking in like 3 spots as it is old brass. i ended up half assing it and kind of getting it to work. It shifted into all three posistions more or less fine. i then started using the motor, put maybe an hour on it, and then my half assed shifting linckage failed. i pulled the boat up onto the beach, took the lower half off, and a lot of water poured out of the lower half. ****. took it to my workshop, put it in the vise, drained the gearcase lube to make sure it wasnt milky. luckily it wasnt, but it was matte black, and smelled terrible. thinking i must have forgotten an o ring somewhere in the water pump, i took it apart again, and when i pulled the drive shaft out, found oil residue that WAS milky. granted it wasnt alot but im still nervous. im thinking that these 20 yr old seals and gaskets have failed, and ive been looking to see what i need to order to replace them, but it just seems like such a daunting task. Hoping someone a little older and wiser can give me a few tips. Im 15 by the way
