Measurement guide: Measure the length of the cable (D), divide it by 30.5, and the resulting number is the length of the cable in feet; finally, round the number. Example: (D)246 : 30.5 = 8.06 = 8FT.

If there is no old cable: For outboard engines, calculate A + B + 90cm, and the resulting number is the length of the cable in centimeters; then divide it by 30.5, and the resulting number is the length of the cable in feet; finally, round the number. Example: (A)50+(B)220+90=360 : 30.5=11.80 = 12FT.
