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

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