My impeller part number is Yanmar 124223-42092 and the gasket is Yanmar 124223-42110. I have never had to replace the cover or cam, so I don't have those part numbers.
Jonathan Indigo 35 III (with 3GMF) Not sure where you are located but Mike in the parts department at Rex Marine in Norwalk CT could not be more helpful. -----Original Message----- From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bill Connon Sent: Tuesday, October 22, 2013 2:48 PM To: cnc-list@cnc-list.com Subject: Stus-List Part numbers for 3GMF seawater pump Group, On haulout this year I noticed water drops from the seawater pump. I changed the bearings and seal and afterwards the pump would no longer self prime. I changed the impeller and was able to pump water using a 600 RPM half inch drill but the boat motor would not self prime and pump anti-freeze through the system. I want to buy a new cover, gasket and cam but can't come up with the proper part numbers. A call to the nearest Yanmar dealer did not help but I assume that it is a Johnson pump ( from what I found on the web ) and it was using a Johnson 827 impeller. The motor is a 3GMF from 1985and the impeller is 2" OD x 7/8" wide and has a 1/2" bore with a keyway. All help with getting the proper part numbers would be appreciated.
