ZERO TORQUE TILLER STEERING SYSTEM
A SAFER WAY TO FISH
Tiller steered boats are labor intensive to steer due to the constant load on the tiller from propeller torque, and the fact that the operator is positioned (while driving the boat) in such a way that maintaining control requires physical effort not customary in everyday activities. The higher torque of today’s four stroke engines has naturally increased the load on the tiller as compared to two strokes. Though engine horsepower on tiller steered boats may not have changed, the difficulty in controlling these boats has increased. Having a system that locks out the torque while the boat is not actively being steered, during fishing, is a desirable feature that has been implemented on larger engines by engine manufacturers.
The solution is the ZERO TORQUE Tiller System which consists of a hydraulic cylinder with a control valve that opens and closes following the operation made on the handle. The valve closes when the steering effort by the driver is stopped; as a consequence the cylinder locks the steering position.
How The Zero torque Tiller Systems Works
When the handle is operated, it swivels around its pivot and moves the linkage bar which will operate the valve.
Push on the end of the tiller handle and the valve opens allowing you to steer.
Pull on the end of the tiller handle and the valve opens allowing you to steer.
Rest your hand on the tiller and the valve remains closed, locking out the propeller torque and providing comfortable boat operation.
WARNING! This system is not intended to be used in place of the boat operator. Operator must maintain contact with the Tiller Handle during operation.
Zero Torque Tiller Steering Features
Suitable for boats up to 150 hp and has a Hydraulic torque lockout. It provides safer boat handling operations. It reduces fatigue from long hours of operate a tiller driven boat.and holds boat direction consistently better than a non assisted power steered boa. With the Zero Torque tiller for Mercury Big Tiller no extra equipment needed including the necessary Power Steering Pump and equipment required to run the standard Big Tiller.
