This spring I noticed a leaking salt water pump on my older ~2003 J109, and I rebuilt the pump on camera. It is a Johnson pump, fitted on the 3GM30FC engine, likely similar to what many who visit this forum have. If you have a similar problem, or if you want to know what it takes to rebuild this little pump, then you'll want to see this video. At the end I included bearing dimensions and ID details in case you decide to save some cash and use generic replacement parts.
