ZTF TILLER SYSTEM
1 PRODUCT DESCRIPTION
1.1 ZTF Tiller System description
The ZTF Tiller System is a hydraulic device that neutralizes the propeller torque of outboard engines on the
tiller handle while the operator is not actively making a steering course change. It enables the operator to
maintain the desired course without excessive physical effort.
The hydraulic valve opens the moment the operator makes a steering course change at which point the
propeller torque will be present on the tiller handle. It is important that the operator maintains a firm grip
on the tiller handle at all times while operating the boat; especially when making steering course changes.
The ZTF Tiller System consists of four main components:
Tiller handle (supplied directly by Yamaha
®
or one of its resellers)
Main device
UC130 ZTF hydraulic cylinder
Hydraulic hoses
