I have a 1989 5.7 with a Alpha 1 outdrive. Up till now I had a guy who maintained boat but it has been sitting out of water ov er a year. I want to replace all cooling pumps / impellars. I have scoured on line and keep seeing a sea water pump which in belt driven and round off to one side...I do not have this. It looks like I have a standard water pump as on a truck? I also believe there to be an impellar on out drive? any help would be great. I am also changing all fluids getting ready to put it back in water.
Thanks, Ralph

The "re-circulating" pump on the engine does not need to have the impeller replaced

The Alpha drive have the rubber impeller inside the drive. So, you have to take it apart in order to replace it.

Bravo drives use a separate "sea water" pump that runs off the engine.
