The motor I am getting ready to go is a 1991 150 Johnson. I went for a spin with the previous owner before purchasing the boat and motor setup. I have previously posted regarding the leaking lower unit . This problem has been resolved. I saw a recent post by Zeltron about his lower unit going bad after rebuild. He stated how it was fried. So before I did my lower unit reseal I of course drained the old grease/ oil from it. There was water in it but upon taking the lower apart all of the bearing seemed to be in good shape. What was odd was the condition of the lubricant. It was actually black and super thick.. I figured that because the boat had sat for so long before we test rode it that the water I saw was new water and that the lubricant was what was left of the old lubricant which we had run with. In the past the lube had leaked out so that we were in fact running with a very low volume. There was almost no rust in the lu. . The only bearing which had any rust I replaced. So now I am wondering what it was I actually saw regarding the tarrish lube. I have been running and shifting the motor at home in a test barrel.
