it's pretty lo tech

Really, the 4 screws. gasket behind the plate. The impeller has a very small snap ring on the end of the shaft. The shaft will also slide out of the pump with the impeller on it. I've not removed the pump yet but i'm sure that's just a matter of take the bolts off the engine. Just be sure your pump is not below the water line and make sure you turn off the seacock so you don't sink your boat. Good luck! Denise
