Quick Take
A rotary steering system turns steering wheel motion into cable motion at the outboard transom. The first question for any shopper is cable length: two of these kits use a 12-foot cable, and two use a 14-foot cable, so the length of your boat's center console-to-transom run decides which half of the group is viable. Wheel size then separates the choices, with diameters from 12.4 to 13.5 inches. The listed prices run from $84.65 to $109.99, so picking the right cable length first can keep you from paying for a longer kit than you need.

Decision Matrix
- Need a 12-foot cable? Look at the two 12FT kits: the 12 Feet Boat Rotary Steering System Outboard Kit & 12Ft Marine Cable SS13712 and the Boat Rotary Steering System Outboard Kit 12FT Boat Cable With 12.4" Wheel. They share the same cable length and wheel diameter.
- Need a 14-foot cable? Choose between the 14 Feet Boat Rotary Steering System w/ Wheel Kit Fit For Outboard Marine SS13714 and the 14 Feet Boat Rotary Steering System Outboard Kit SS13714 Marine With 13.5" Wheel.
- Want the largest steering wheel in the set? The 14 Feet Boat Rotary Steering System Outboard Kit SS13714 Marine With 13.5" Wheel offers the 13.5-inch wheel; the 12-foot kits come with a 12.4-inch wheel and the other 14-foot kit with a 12.5-inch wheel.
- Want a direct-replacement style? The 14 Feet Boat Rotary Steering System w/ Wheel Kit Fit For Outboard Marine SS13714 is designed as a direct replacement with an interchange part number of SS13714.
Product Notes
12 Feet Boat Rotary Steering System Outboard Kit & 12Ft Marine Cable SS13712
This kit bundles a 12-foot cable, a 3/4-inch tapered shaft, a swivel helmet, a 12.4-inch steering wheel, a 90-degree bezel kit, and hardware. It is new and made in the United States, and it uses the SS13712 reference number, which makes it easy to match against the other 12-foot kit in this guide. The practical limitation is the length itself: if your boat needs a longer cable run to the transom, this kit will not be the right fit. When 12 feet is the right reach, the bundle is complete and self-contained.
Boat Rotary Steering System Outboard Kit 12FT Boat Cable With 12.4" Wheel
This is the other 12-foot system, using the same SS13712 reference number, the same 12-foot cable, and the same 12.4-inch wheel. The steering cable is designed to meet precise steering requirements for different types of rudders and cylinders, so it is a reasonable match when replacing older steering hardware. The limitation is the lack of differentiation: the bundle contents are effectively the same as the first 12-foot kit, with only the listing wording and listed price separating them. If you are simply choosing between the two 12-foot kits, the decision comes down to which of the two kits you want to start with.
14 Feet Boat Rotary Steering System w/ Wheel Kit Fit For Outboard Marine SS13714
This 14-foot kit includes a 14-foot cable, a standard 3/4-inch tapered shaft, a swivel helmet, a 12.5-inch steering wheel, a 90-degree bezel kit, and hardware. It is designed as a direct replacement, and the alloy construction is built to resist corrosion and rust, which is relevant for marine use. The trade-off is the wheel size: at 12.5 inches, it is smaller than the 13.5-inch wheel on the other 14-foot kit. If a larger grip matters more than the direct-replacement design, the other SS13714 kit will be the stronger candidate; if corrosion resistance and a direct swap are your priorities, this one covers them.
14 Feet Boat Rotary Steering System Outboard Kit SS13714 Marine With 13.5" Wheel
This kit combines the longest cable in the group with the largest wheel: 14 feet of cable and a 13.5-inch wheel. The listed materials include cast steel and stainless steel, and the item weight is 15 pounds. The SS13714 reference number matches the other 14-foot kit, so the deciding feature is the bigger wheel. The limitation is that the larger wheel and longer cable only earn their place if your boat actually needs a 14-foot cable run; for a shorter run, the extra cable is simply excess.
Final Recommendation by Use Case
For a 12-foot installation where the full SS13712 bundle matters, the 12 Feet Boat Rotary Steering System Outboard Kit & 12Ft Marine Cable SS13712 is the cleanest starting point. If you are replacing a 14-foot direct-replacement helm and want the corrosion-resistant alloy build, the 14 Feet Boat Rotary Steering System w/ Wheel Kit Fit For Outboard Marine SS13714 is the version to compare. If a large steering wheel is your priority and the boat can use a 14-foot cable, the 14 Feet Boat Rotary Steering System Outboard Kit SS13714 Marine With 13.5" Wheel is the one that stands out. That leaves the Boat Rotary Steering System Outboard Kit 12FT Boat Cable With 12.4" Wheel as the alternative 12-foot option when the same cable and wheel dimensions work for your setup.
