I just replaced the impeller on my Alpha One Gen 1 and ran into a couple issues.
When installing the pump base, I had a heck of a time getting it to seat fully, and level. I ended up going back to the stock base as it looked like the new one had developed a small crack. I’m fine running the old base as there were no issues with the pump, but the impeller change was long overdue. Even with the old base, I could see light between the base and the lower unit housing on the aft side of the pump/lower unit, the flat side. This just doesn’t seem right, but even the old base is doing it (all new gaskets). Trying to eliminate the gap is how I think I cracked the new pump base. Am I wrong in assuming it should actually seal?
Also, it appears I have developed an oil leak and am getting oil out of the weep hole. I took the top back off the lower unit and there’s a puddle of gear oil sitting on top of the water pump. I can only assume this is coming from the upper half of the unit and leaking past the o-ring on the drive shaft. Is there any other place it could be coming from?
Obviously, I’m fairly novice at doing out drive work, so I’m learning as I go.
Also, after taking the lower unit apart this second time, a couple washers dropped out. Looking at the parts diagram, it appears they go on the shift shaft. Does it matter which order they get installed?
