ZTF Tiller MC1 -  Mercury Conversion ZTF Tiller

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 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 to 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.

This item is just the kit that includes Cylinder, Valves, Hoses and Bracket to convert a Big Tiller to a Zero Torque Steering. Tiller Handle must be sent into for retrofit. Please contact sales for more information. The shipping cost shown is for return shipping after retro-fit has been complete and returned to customer. We also offer the complete Tiller Assembly ready to go. See ZTF Tiller Assembly Complete. Lead Times are 3-6 weeks with shipping.

Note: The tiller arm will increase in length up to three inches from original size due to the bracket that gets installed during the retrofit. This can cause the current T/S cables to be short when reinstalling Tiller. Customers will be required to replace the original T/S cable's with longer ones, which can be purchased from your local Mercury Marine Dealership. See chart below for T/S cables replacement. These parts are not included in the retrofit.
