Propeller Shaft Diameter Measuring Tape

Shaft diameter measurements made easy!

Designed to accurately measure boat propeller shafts from 3/4” to 5” in diameter, or 25mm to 100mm in diameter. This measuring tape is for use underwater by divers, or “on the hard” and in the engine room by owners and service personnel.

Instructions:

• Wrap tape tight around propeller shaft.

• Tape is calibrated to directly read the shaft’s diameter. (shaft diameter = shaft circumference / 3.14)

The white tape is made of DuPont Tyvek™ material. It is waterproof, stretch proof and tear proof – yet very thin (only 0.006” thick). It is printed with black indelible ink that’s smudge proof and with high contrast – perfect for the underwater diver.

The tape includes both Inches and Millimeters measurements and is precision marked and end-cut, making it accurate enough to even discern the difference between a 1” and a 25mm shaft. (Tip: multiple wraps helps with this close one.)
