When I'm doing Water Pump Impellers on the 225's and up I do too. I just had to drop this one enough as I got the shift spline timing off and thought it would be a good time to show some of the membership that you don't have to sit there and hold it while removing the retaining bolts. I don't know how I got the spline off but I must have moved the linkage while the Powerhead was off. The linkage secures to the Powerhead, I had to clean the Base Flange again real good. I got the Crud too so doing I'm this with medicine head.
