I picked up an 8hp Johnson/Evinrude last year. Fortunately, it came with a boat. Looks like the lower unit is taking in water. It didn't have a gasket on the upper drain screw, so I hoped that was the problem. Not to be, it's still getting water. So, it looks like it needs the seals replaced. I can either do it myself or have someone else do it. 1. If I do it myself, any thoughts on about how long it'd take? I figure I'd probably want to replace the impeller while I'm in there. A couple of factors get in the way of doing it myself. Mostly, I don't have a lot of free time and my wife has an unreasonable expectation about engine parts on the best working surface in the house which is the dining room table. 2. Any recommendations on someone to do the work in the Washington County area?
