I recently picked up an 81 Johnson 15hp cheap, and this weekend after a carb clean got it running (starts first or second pull and idles smooth). The problem is that there is no water flowing from the tell tell when running in the driveway on muffs. Suspecting a bad impeller, I pulled the lower unit but the impeller appears to be in new condition and the housing looks to have been replaced recently as well. There was still some grease inside the impeller housing, so my guess is the previous owner replaced it thinking it was the problem. Put it all back together and still no water from the pee hole.When running on the muffs, water is pouring out the the hole in the lower leg that the shift linkage passes through. Not sure if this is normal when running it attached to a hose?
Is it likely that there is a blockage inside the engine causing this, and if so, where should I be looking? I pulled the rubber hose running from the engine to the pee hole and it was clear.
Thanks in advance for any help you can give me here. As i said, I picked the engine up cheap but don't want to put much money into it.
