Re: 200 efi 2001 impellar replacement
You need to drop the lower unit. The water pump is driven by the drive shaft and is located at the top of the lower unit. To prevent messing things up, you should really buy a service manual specific to your engine (preferably the factory version) if you plan to do any service of this type yourself. If you don't want to buy one, check your library -- they often have manuals although they would be generic or possibly cover an entire range of engines. Most service procedures like this are far too detailed to expect anyone to outline here.
