Teleflex Marine offers a wide variety of mechanical steering systems in both Rack and Rotary designs. If you have the space behind the dashboard to accommodate a rack style system we recommend choosing it over the rotary design. You can see from the pictures below that the rack takes up about a foot on each side of the helm. Therefore you must have clearance between the helm and the side of the boat to utilize a rack system. The rotary systems are much more compact and fit in tighter quarters.
The correct way to measure steering cables: If you are replacing a Teleflex, Morse, or other brand of cable or complete system the first thing you need to determine is the length of the cable your install will require.
For Rotary systems: Measure the jacket length, add 18 inches then round up to the nearest one foot increment.
For Rack systems: Measure the jacket length, add 30 inches then round up to the nearest one foot increment.
If you are doing a fresh install, route a piece of rubber fuel hose or equivilent where your cable will go. Measure the length and estimate what the jacket length will be and order appropriate length system.
