• Speed, hull, horsepower, engine type, displacement and size are major factors in boat performance and handling characteristics. The above selection guide should be used as a general reference only. • One of the major factors in selecting a steering system is proper cable length. Due to a specific routing in each boat, these approximate lengths will vary. Final selection should be made with the assistance of a qualified installation mechanic. • Ultraflex mechanical steering systems should not be used on boats equipped with engines that exceed the maximum horsepower rating of the boat. HOW TO MEASURE FOR NEW STEERING CABLE INSTALLATION

Add: A + B + C and subtract 10cm (4") for each 90° bend in the cable. For installation through the engine tilt tube, add 30.5cm (1ft) to the measure calculated above. Aquafax stocks M58 and M66 steering cables in foot length, to order divide by 30.5cm (1ft) and round off to the next whole foot.

TILT TUBE MOUNTING - FIG. 1 Example (dimensions in cm): A(50) + B(250) + C(80)= 380 – 20 for two 90° bends = 360 + 30.5 For a thru-tube installation = 390.5cm ÷ 30.5 = 12.8ft; round off to 13ft.

TRANSOM SUPPORT OR SPLASH WELL MOUNTING - Fig. 2 & 3 Example (dimensions in cm): A(50) + B(250) + C(80) = 380 – 20 for two 90° bends = 360 ÷ 30.5 = 11.8ft; round off to 12ft.
