I have an 83 Bayliner with a Volvo 260 and I think an aq270 or 280 outdrive and need to find out about changing the Iimpeller. Any help would be appreciated.
The impeller is located in the pump mounted to the harmonic balancer. Remove the brass screws holding the cover, carefully pry the impeller out using a couple screwdrivers being careful not to damage the pump housing, install the new impeller. Don't worry about the new impeller fins being in the correct position since they will correct themselves once the engine turns over. Dont run the engine without water flowing to the impeller.
