9. Steering 350/351 The principle of the Cobra™ steering system is based on the precision gearcut circular rack and pinion in the head of the pedestal providing the necessary mechanical advantage (see wide angle geometry). The quadrant gear is connected to a stainless steel downtube, at the base of which is an output lever. This connects to a similar lever, mounted on the rudder stock, via a fully adjustable draglink. All shaft work is carried through high-efficiency sealed ball races and the mesh of gears is controlled via shims under the input, eliminating any lost motion. The input socket also houses a powerful and progressive friction brake for dampening the wheel, when at anchor, for example. Cobra™ Systems With over 40 years technological development, Cobra™ has become the first choice for boat builders worldwide for aft cockpit vessels. Cobra™ systems are the world leader in terms of performance, reliability and appearance for Rack and Pinion. Principle of Operation ▪ ▪ Typically designed for aft cockpit boats with a short distance between the helm and the rudder ▪ ▪ Simple installation providing a direct feel and rudder response ▪ ▪ Adaptable for twin helm / twin rudder solutions ▪ ▪ Compact installation for boats with minimal space available ▪ ▪ Strong and light – no parts to fret or chafe ▪ ▪ Minimum maintenance ▪ ▪ Smoother operation ▪ ▪ Greater torque capability ▪ ▪ Full CE Certification available
