In marine steering controls, the cable run from helm to outboard is the key variable when choosing a rotary steering kit. The 12-foot SS13712 kit lists at USD 85.99, while the 14-foot SS13714 kit lists at USD 96.92, so the longer cable costs about USD 10.93 more. Both kits target mechanical or manual steering for yachts, fishing boats, and other waterborne vehicles, and both come with a rotary helm, a 3/4-inch tapered steering shaft, a bezel kit, and cable mounting hardware. Your boat's layout, not the included components, will likely decide which one fits.
Quick verdict
If your steering cable run is close to 12 feet, the SS13712 kit is the direct match. If you need a 14-foot cable, the SS13714 kit is the one that provides the extra length. Both are new rotary steering kits with a 3/4-inch shaft, so the practical difference is reach.

- The 14-foot SS13714 wins when the route needs extra reach. The 14-foot cable, identified as 4.27 m, makes it the more suitable choice for a longer run.
Product notes
12 Ft Boat Rotary Steering System Outboard Kit & 12Ft Marine Cable SS13712

The JDMSPEED 12-foot kit is built around a 12-foot steering cable and a 3/4-inch tapered shaft, with a rotary helm, a 90-degree bezel kit, and hardware included. Cast steel and 304 stainless steel seamless pipe make up the steering system, with corrosion-resistant materials, and the mechanical/manual steering setup suits yachts, fishing boats, and other waterborne vehicles. This is the kit to pick when your cable route stays within a 12-foot run. The limitation is the cable itself: at 12 feet, it won't bridge a longer helm-to-outboard distance, so if your boat needs a longer reach you'll be looking at the 14-foot alternative.
14 Feet SS13714 Boat Rotary Steering System Outboard Kit 14Ft Marine Cable

The 14-foot kit comes with a 14-foot steering cable, a 3/4-inch tapered steering shaft, a rotary helm, a bezel kit, and a fixing bolts and screws kit. The cable is identified as 4.27 m, so the package works for metric measurements. As an aftermarket part with reference SS13714, it fits the same mechanical/manual steering applications on yachts, fishing boats, and other waterborne vehicles. The additional two feet of cable is what makes it useful for a longer run; if your helm-to-outboard distance is anywhere near 14 feet, this is the one to choose. If your route is closer to 12 feet, the extra length may be more than you need.
Final choice by use case
For a 12-foot cable route, the 12 Ft Boat Rotary Steering System Outboard Kit & 12Ft Marine Cable SS13712 is the clear match. For a 14-foot cable route, the 14 Feet SS13714 Boat Rotary Steering System Outboard Kit 14Ft Marine Cable is the one that fits the run. Since both kits share the rotary helm and 3/4-inch shaft design, the practical tie-breaker is cable length; choose the one that matches your boat's actual distance.
