Hynautic Hydraulic Controls Let's See What We Have Here

Hydraulic Control Systems

  • TeleflexMorse is the world's largest manufacturer of marine hydraulic controls
  • Proven performance and reliability for over 30 years
  • Dependable control for luxury cruisers, workboats and commercial fishing boats
  • Nothing moves boats better
  • A hydraulic control is a liquid link between a sender and an actuator
    • Provides pure energy in motion
    • Without friction
    • Without backlash
    • No lost motion
  • Up to four stations is possible depending on length of tubing run
  • Unique and highly accepted feel
  • Simple installation

Multiple Station Synchronization
Each Hynautic sending, unit contains a special valve assembly which permits full synchronization. With just a few movements of one handle, all stations are synchronized. Any adjustments are automatically made as the system is operating.

Ease of installation
Unlike bulky mechanical or cable systems, Hynautic uses lightweight nylon tubing which is more pliable and less susceptible to abrasion. Components are easily mounted and the senders are hydraulically connected to the slaves, avoiding the troublesome linkage boxes found in mechanical* systems.

No Throttle Feedback
By incorporating a double check valve in the system, throttles cannot be retarded by heavy-duty governor springs common to most large engines. Quick disconnect linkage at the engine allow for independent throttle operation while servicing the engine.

Quality Materials
All component bodies are made of 6061-T6 aluminum. Sender heads and handles are anodized aluminum; sender shafts are stainless steel. Cylinder barrels are brass.

Neutral Clutch Detent
A spring-loaded clutch detent on each clutch slave insures that all stations register a distinct feel when the transmission is in neutral. Also available is an optional Neutral Safety Switch Kit which prevents the engine from starting while transmission is in gear.

All Hynautic control systems' incorporate certain high-tech components. These hydraulic components are interconnected either nylon or copper tubing.

CL-B4 or CR-R4 Senders
Separate left and right sending units are interchangeable as either clutch or throttle controls. The sender face is brushed anodized aluminum, as is the handle. Optional mounting plate simplifies side-by-side installation.

R-13 Reservoir
The reservoir maintains the fluid reserve and pressure for the hydraulic system. Clear sight tube makes visual fluid inspection easy. The lower charging valve section keeps all parts of the system under positive fluid pressure.

Transmission slave with neutral detent is mounted directly on the transmission.

Throttle slave directly attaches to the engine's throttle linkage. It is equipped with a pilot check valve to prevent throttle feedback.

A Guide Hynautic Controls
When the control handle of the Sending Unit is moved, mechanical energy is transformed into fluid energy by means of a rack and pinion attached to an internal piston. This piston expels fluid from the sending unit into all other control heads and the slave unit. The pistons in each of these units are thus moved an equal distance, causing a corresponding movement in the lever of each.
To control synchronization, the piston; in each sender and slave contains two small valves. These are opened when the piston reaches the end of the stroke, allowing excess fluid to pass through the piston and into the system. Controls can be synchronized, if necessary, by rotating the lever arm of any control head from stop-to-stop.
The Reservoir maintains the extra fluid and constant pressure head (80 psi) for the system. The flow of fluid to and from the reservoir is regulated by small valves located in the charging section. As fluid expands due to engine temperatures, the excess liquid is expelled into the reservoir at a controlled: rate. Likewise, fluid is returned to the system as temperature drop.
Each Slave Unit contains an over-travel bungee in its linkage to the engine or transmission. This device assures that the slave piston will reach end stroke in each direction. Otherwise, the balance between senders and slave cannot be maintained. The transmission slave unit has a mechanical detent to indicate a neutral position. Each throttle slave-is equipped with an internal pilot check valve which prevents control arms from drifting back to an idle position.
