I know it's a Stewart Warner gauge panel, oil temp, oil pressure, water temp amp and tachometer. What does it fit, what year, etc.
With a tachometer that only reads to 2400 RPM, it probably came from a boat. Likely from one that was diesel powered with a closed cooling system.
Good call on the diesel. What else would run such low RPMs? There may get be something, but I can’t think of it. Other interesting thing is water temp, max reading is fairly low. Is this a boat thing?
There was a SW thread on here somewhere. Has lots of good pictures. As clean a unit as it is did it come off a shelf in a forgotten corner?
That's really about it. Normal operating rpm on a Yanmar or Perkins is between 2300 - 2500. They are capable of 3000, but that RPM isn't necessarily going to help a boat's speed. It will just burn more fuel.
Is this it??? https://www.jalopyjournal.com/forum/threads/stewart-warner-gauge-panels.219140/ Looks like @Paul had one just like it. Check out post #78 in the linked thread. He might know what it is.
sorry, can't help other than the seller said his father bought it new to put in a boat that never got finished
The picture on post 78 looks to be the same panel. If I'm reading the part numbers correctly mine was manufactured in 1943. There is one on Ebay right now that the seller states his was made in 1951. The gauges in his look to be newer design and the temp gauge doesn't have the red line
