Changing the impeller on a Johnson 70 hp outboard motor requires pulling the power head and disconnecting the engine. Once this is done, an open end wrench can be used to first loosen the fitting before removal.
To fix your 25 horsepower Chrysler impeller, you will first need to find out what is wrong with the impeller. If it is clogged, you might simply be able to blow the obstruction out of the impeller. In some cases it will require replacement.
Propeller is external (outboard motor on a boat) Impeller is internal (vehicle water pump).
Take the cap off, there is a nut with a cotter pin in it. Remove the pin and unscrew the nut.
First, remove the lower unit (there is a housing for the water pump). The drive shaft goes through the housing and turns impeller. Remove the housing, the impeller is on the shaft. Install the new impeller. When replacing the housing, turn the drive shaft clockwise to make it slide down over the impeller.

how do you change the impeller on a Johnson 9.9 out board motor
The water pump impeller on a 7.5 hp Mercury outboard, is located on top of the gearcase, and is driven by the driveshaft.
The impeller is located inside the water pump housing, on the topside of the gearcase. The gearcase will have to be removed in order to service it.
Depends on what you mean by service it? Change spark plugs, change lower unit oil, change impeller & thermostat, check 20 amp fuse, FULL decard, compression check, etc.....
Change the water pump impeller, they get old and need replacing every 5 years or so depending on wear.
