Have not rebuilt the water pump on this specific engine, but have done a lot of my own mechanicals like rebuild carbs and rest of fuel system, oil pumps, shift cables, etc, so I think I can do this except I'm in my early 70's and not as strong as I used to be. So my question is whether anyone can give me a "ballpark" on the weight of this lower unit? Any tips on how I can secure the unit in place while I remove the water pump bolts and torque back in place? It seems to big/heavy to mount in my 10" vise. One last question, is this going to be a 2 man job to align everything while reattaching the unit.
