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

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