[AT] [External] Mystery port on Super M water pump

[Gunnells, Brad R]

I can’t say for certain, but a friend of Dad’s had a Super M that had been restored. It actually had a heated seat. There were heater hoses that ran from the engine up to the seat pan. There was a valve at the seat where you could adjust the coolant flow (to adjust heat I presume). I would guess your elbow could likely be for something like that.

I wish I’d taken a picture of the seat and the setup. It was an interesting setup.

Subject: [External] [AT] Mystery port on Super M water pump
The other evening I happened to notice this little pipe elbow sticking out of the side of the water pump on my Super M, and I realized I had no idea what it was for.   Couldn’t find it in the operator’s manual, and photos of new replacement water pumps don’t show any port there.   A well-done farmer mod, perhaps for purposes of adding a block heater?  Or for circulating hot water through something else?   Anybody ever seen one in that location?

Thanks very much,
