Yanmar 2GM/3GM commercial water pump parts

I noticed in the "Maintenance" section of the website there are details of aftermarket parts for the Yanmar 8hp engine water pumps. I thought it might be useful to someone to know the details for the 2GM/3GM series (so they spend about $15 instead of several times that on OEM bits).[These parts are from the likes of CBC Bearings]

The bearings are: NSK 6200ZZCM NS7S 605

The seal is : NOK AEO279A

And of course you need to replace the seal spring with an O-ring - the bearing shop will do that for next to nothing.
