The base measurement is 360cm minus 20cm = 340cm. For tilt-tube mounting, add 30.5cm: 370.5cm divided by 30.5 = 12.15, so select a 13ft cable. For transom-support or splashwell mounting, 340cm divided by 30.5 = 11.15, so select a 12ft cable.\u003c\/p\u003e\n\u003cp\u003eIf replacing an existing Multiflex cable, first inspect the jacket for its reference.
