Author Topic:   Teleflex steering in a Nausett console

I have built a Nausett-spec console for my 17' hull (emerged from factory as a Sport) and am getting ready to rig it.
Questions:
-What is the specified minumum bend radius for Teleflex cables?
-Anyone with a Nausett console, can you describe the cable path through the console down into the tunnel. Was the factory cutout used or was a new hole cut.
-where does the front of the console sit in relation to the tunnel entry? just in front of the opening?
-any other words of wisdom on rigging?

Carl: Good questions.

The tunnel hole is close to the front of the console base. Give me a call over the weekend and I measure the cleat spacing in relation to the tunnel opening. But in general, it is very near the front.

The bend on cables is indicated in the teleflex directions. I just replaced mine with the same NFS system they are using in the new Montauk's. It is the appropriate set-up for your Nauset. I believe the radius bend is recomended to be no less than 8", but I wouldn't swear to it. Again, I have that info readily in my shop.

The hole in the lower console unit is in fact the appropriate routing hole. The way mine was originally routed, the cable exited the helm unit, ran near the face of the starboard side of the console dash, looped back around and down, ultimately entering the trap door in the lower console.

BTW, on the new NFS systems, the connection for the cable extends further back away from the face of the dash. This now causes a slight problem of the steering cable interfering with the binnacle mount as it protrudes through the console. It's the old physics problem of two items trying to occupy the same space at once!

One fix would simply be to mount the binnacle farther forward away from the the "dash". The solution is not practical as it places the binnacle controls too far forward when operating the motor, making one reach.

Another fix is to rotate the helm unit 180 degrees so that the connection ports are located on the port side. Be careful to now insert the cable on the lower of the two connection ports (this is critical due to the torque effect) and the plastic overrun tube on the upper connection port. The practical problem here is that the cable, since it is connected to the lower of the two ports, hangs lower and may interferes slightly with access to the console shelf. I
Not a bad tradeoff in my mind. One does need to be careful to use cable ties to hold the steering cable in place so that it cannot flop around and damage any electrical connections coming off of the port dash panel.

I guess another solution would be to try to bend the cable around the protruding binnacle base, but that creates the practical "radius" problem and make may the steering more difficult and more prone to premature wear.

I wonder if any other Nauset owners that have changed steering systems and binnacles (I have moved kicking and screaming from the original Morse control to the Yamaha) encountered the same dilemna and how they may have handled the issue.

It is quite astounding how may problems you need to puzzle through when building a console from scratch in a boat that did not have one.

I had not yet made the cable cutout panel in the shelf when it occured to me that the factory location might not be the best place for a hole given the paticulars of my rigging. In the case of the Yamaha binacle you simply cannot make the bend within spec without either shiming the control straight up or at an angle. So for the binnacle I am going to cut a hole where the cable wants it to be rather than bending the cable to conform to the factory spec hole.

For the steering I suspect I will take the same approach. I will have the cable going off to the left to avoid the binnacle which--as you observed--would need to go too far forward to allow the cable to pass. btw, the Teleflex web literatue shows the unit in this orientation, namely, cables off to the left. So the path I end up with is to pass over the tach, make a turn and then angle down at 45 degrees passing though the shelf on the left side at the midpoint front to back. From there it will curve down into the tunnel. This will give me nice, lazy curves and keep the cable more or less out of the way.

I just found the spec for bend radius on the Teleflex site: 3 inch minimun radius. That sounds awefully tight. The Yamaha cables call for 8 inches.

Carl:

I just found the instructions from the Teleflex SH4910 that I installed. It says in both bold and capitals and I quote: DO NOT MAKE BENDS OF LESS THAN 8 INCHES RADIUS. Hope that helps.
