L124C is on a distinguished road
I got the parts from the local Yanmar dealer. Strange thing is, the parts diagram (see picture) calls for 2 bearings (#7) and 1 oil seal (#8). No water seal. The motor is a 2GM20(F). I questioned the lady at Yanmar about it and she showed me the diagram (which she had nicely copied for me) and correctly said "your looking at the same thing I am". This makes me wonder, what keeps the water in the pump, and if I don't have a water seal, whats leaking? I could pull it apart, but have a race coming up and don't want to unable to get a part. Ideas?
