CHRYSLER IMPELLERS
To install impeller, flip the housing upside down and turn impeller down into housing in direction shown: (lubricate inside of housing first with a film of outboard oil or other lubricant) then flip housing right side up and slide down driveshft. Rotate the driveshaft CLOCKWISE until the keyway mates with the impeller so housing slides all the way down and install housing to gearcase. Impellers are impeller only, no gaskets, unless noted.
