That is very ingenious, sir, and it displays the amount of thought and skill that was put into making the gauge. Love the logo and your signature on the dial face.

***************

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.

The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.

Thanks Bill.  It took a few hours on Photoshop using the ink dots on the left image circumference as reference points.

5 PSI = 20 MPH; 11 PSI = 30 MPH; 19 PSI = 40 MPH; and 30 PSI = 50 MPH

As you can see the progression is non linear requiring a bit of poetic license to increase the graduation spacing moving each one individually and resetting its angle in line with the radius. 

The challenging part was prying off the bezel and crimping it back on without damage.
