I have a 1979 115hp Evinrude outboard. We're
trying to change the impeller. We removed a
bolt which held the top of a shaft in a bracket
in the top part of the motor, then removed 5
bolts from the lower end and tried to drop it down,
but it is stuck somehow. Can anyone offer any
advice on this, and/or know of a place online
where there's a diagram or explanation of how
to change an impeller?

Thank you for any help!
