Requests for tips to remove impeller on 4JH Yanmar

[Shrew]

On my Yanmar one of the bolts for the water pump">raw water pump can't be removed without removing an engine mount first. However, you can remove all of the bolts enough to free the pump itself. This allows the one bolt to remain inside of the flange for the pump and giving the pump and bolts clearance to be removed without touching the motor mount.

I like it this way. It's way easier to replace the impellor on a bench.
