second hole is for the shear pin and prop without he clutch hub. just the prop look in the prop and you will see the cut out for the shear pin.
January 31, 2021 at 2:17 pm #229190The clutch gets driven by the same pin that drives the impeller. The second hole in the shaft, seen in your picture, is not used when there is a clutch. That hole would be for a shear pin to drive on the propeller directly, with no clutch.
Long live American manufacturing!
January 31, 2021 at 4:33 pm #229199Yup thanks. All makes sense now. Now I’m looking to replace the seal in the pump housing. How in the heck does one get that out?
January 31, 2021 at 4:56 pm #229200Bill the clutch is not driven by the impeller pin the 2 holes are outside the pump.. one for the clutch and one for prop without clutch as I have said ..
February 1, 2021 at 5:23 pm #229244Any tips on seal removal?
February 1, 2021 at 6:01 pm #229247tap it out from behind with a hammer and screwdriver.
February 1, 2021 at 6:55 pm #229248And if you can’t get on it from the back? Brass bushing in the way.
February 1, 2021 at 11:05 pm #229269Removing the old seal is not a neat and tidy affair for me. I use hammer and punch to beat in the rim of seal so I can grab on it with nippers and bite off pieces. There probably is a neat and clean method other have discovered, but. not shared. Not a difficult job, just time consuming.
The real problem is that the old hard seal has worn a groove in the prop
shaft so a new seal will not work or last.

It seems to me the lower unit illustration is for later type lower unit
not KD4 type.
