1 PRODUCT DESCRIPTION
1.1 ZTF Tiller System description
The ZTF Tiller System is an hydraulic device that counters the propeller torque of outboard engines on the tiller
handle while the operator is not actively making a steering route change. It enables the driver to maintain the
right route without relevant physical effort.
The hydraulic valve gets opened when the operator makes a steering route change and the propeller torque is
present on the tiller handle. It is important that the operator keeps a firm grip on the tiller handle all time long
while operating the boat; specifically during steering route changes.
The ZTF Tiller System is made of four main components:
1
Tiller handle (supplied directly by the engine man-
ufacturer or any dealer)
2
Main valve device
3
UC130-ZTF hydraulic cylinder
4
Hydraulic hoses
NOTICE
The ZTF Tiller System is always supplied oil-filled, purged, functioning and with properly connected hoses.
CAUTION
Avoid twisting, damaging, bending and disconnecting the hoses.
CAUTION
The ZTF Tiller System is meant to be used with:
- Mercury Marine outboard engines of the 75 through 115 horsepower EFI four stroke family of engines built since 2014.
- Yamaha outboard engines of 90-115-130 HP produced from 2015 to date, and engines of 150-175-200 HP - models 2.7L
F150 Mechanical, VF150 V MAX SHO, F175, VF175 V MAX SHO, and F200 Mechanical
- Suzuki DF150A/175A/200A
and must be installed only on boats specifically designed and suitably equipped for being steered with the tiller
handle. The installer and the driver are responsible for ensuring the proper functioning of the ZTF Tiller System
on the boat, bearing in mind factors like speed, torques and working conditions.
CAUTION
Do not use this device for purposes other than those it was made for, as specified in the installation manual.
