Today’s four stroke outboard engines are generating high torque loads which can make tiller steered boats difficult to steer. The Ultraflex® ZTF Tiller systems eliminate propeller torque at the tiller handle when the driver is not actively changing direction.
Using a patented hydraulic valve, the propeller torque is locked from reaching the tiller handle unless the driver pushes or pulls on the end of the handle, at which point the valve opens and allows for active steering movements.
Now you can drive your tiller steered boat in comfort, saving your energy for reeling in fish rather than effort to just get to your favorite fishing spot.
HOW THE ZTF TILLER SYSTEM WORKS
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.
