Description
The T73 NRFC mechanical steering system has been designed to control boats equipped with outboard, inboard, or non power assisted stern drive engines.
Steering system T73NRFC is used for single cable steering helms and must be used with Ultraflex M66 steering cables.
The T73FC Steering System features a Planetary Gear Design. Three satellite gears rotate on their axis and at the same time rotate around the central helm axis. This allows for equal distribution of engine torque over three points of the central gear, dividing and balancing the system loads. The benefits of this special design are increased system longevity, increased efficiency and less engine feedback compared to single pinion gear helms.
The T73NRFC Steering System is also equipped with a Non-Reversible System. It is made up of a special patented device which allows the helm shaft to lock until turned by the driver, maintaining the boat direction and neutralizing the feedback loads on the steering cable. The Ultraflex non-reversible mechanism makes driving a boat safer and easier.
The T73FC steering system is not to be used on boats equipped with engines that exceed the maximum horsepower rating of the boat and/or the speed of 50 knots .
