This rubber piece fell out of the back end somewhere when I was taking the jet pump, propellor etc. off & I’m in the process of putting it all back together & have no idea where this goes. Any help?
I hope you figured out where it goes. It seals the water connections on the jet pump and there are (3) of them. A little RTV on installation is recommended. Don't forget the rubber bumpers on the drive shaft. Those need to be on there too and can be a pain to keep in place when installing.
