| Author | Topic: Wire Rope and Pulley Steering |
| johnnylaing |
My [1968--pleaese use four digits for years--jimh] [Boston Whaler] 13 has two padeyes on Starboard and one on Port. How do I install [wire rope] and pulley steering with one Starboard spring, as is Whaler's recommendation? It seems like I'll need an additional padeye on each side to terminate the 3/16-inch wire rope, but maybe I'm missing something. Possibly this was a tiller steer boat. Also do the pulleys attach directly to the pad-eye or use some type connector? [Seeks] pictures from an original [wire rope and pulley steering installation on a classic Boston Whaler 13-footer]. I'm not doing Teleflex. thank you! |

[T]he cables can terminate at the motor. [I] don't honestly recall if that is how [Boston Whaler] did it [as it has] been too long since I rigged that cable steering. |

Not to mention that there's there's a crude, rugged, reliable practicality in rope and pulley. Good features in a boat. Particularly a salt water boat. Anyway, well done. -Peter |

The padeyes are for the pulleys, not for terminating the cable. Two pulleys on the starboard side and one pulley on the port side. The cable ends terminate at the motor with the starboard end terminating at the single spring attached to the motor. |
| Tom W Clark |
Actually looking back though the catalogs, I see that by the 1970's Boston Whaler added pulleys to the motor attachment to "gear down" the steering. On those boat there was an extra pad eye on each side of the boat. |
| johnnylaing |
I'm following. And the connection to the pad-eyes? I have three pulleys that are contained in a flat steel bracket(no swivel) and two (that attach to the motor bracket) that have a swivel hook. Thanks in advance for the help, and pics would be great! I've looked and looked to find an original picture showing the rigging. |

Thimble and two cable clamps on each end. |
| johnnylaing |
OK--at the two ends. Starboard: spring,thimble,two clamps Port: thimble, two clamps What I was not specific about was the three pulleys- how do they attach to the pad-eyes? I just did a dry fit and it appears they will not have much clearance without some kind of link. Again, anyone, are there any pictures in existence to share? |

Nice, Binks. Classic'o'rama. My old Big Twin,'59 Super Seahorse 35hp, had a similar looking, quarter-turn-fastener attaching to the "handle" on the front of the engine. Of course, most of the cabling was hidden underneath the gunwales and the splashwell on the semi-finned fiberglass runabout. -Peter |

Did you have to drill into the modern Merc to attach the steering bracket? -Peter |
| johnnylaing |
I notice two springs while Whaler says one on starboard, so...one or two springs? Thanks for all the replies... |
| Binkster |
Peter No there are two convenient tapped holes that I just bolted a homemade connector to made out of 3/8" aluminum angle. Don't remember what the holes are for. johnny There is no torque steer when using cable and pulley steering. The wheel won't turn if you remove your hand when running. On outboard powered raceboats, cable and pulley steering is the only type of system allowed as it it basically fool proof and easily inspected. The difference is that raceboats use a steering bar which is bolted to the back of the engine and bend around as far as the swivel tube, as seen here on my Chrysler 105hp powered Class F Racing runabout. No spring is needed here becuase the tension remains the same if the engine is tilted up. |

Wow, that writing style seems like it is from another century. I interpret the verbose sentence explaining "half time" steering to mean that it makes the steering less sensitive- is this what they mean? I have mine rigged to a 2007 Yamaha 4 stroke 20hp, it has an adapter plate, one spring, and pulleys at the motor. I will try to post pictures if I get a chance. |
| tjxtreme |
Duh... correction- the 1800s. |
| Tom W Clark |
That is the voice of Dick Fisher himself. The catalogs from the 1960s are full of those editorial comments and bon mot. I love them. "half time" = 2:1 mechanical advantage. |
| Binkster |
I don`t get any oscillating back and forth using two springs on my 4 stroke 25 or my 2 stroke 1961 75hp Evinrude V-4 at all. Maybe the springs they used back in the 60's were not as stiff as modern ones. No way I could compress the spring(s) half way let alone 3/4 way with modern springs. If I did and used one spring and compressed it 3/4 way the cable would be as tight as a guitar string, and I probably couldn't tilt the motor at all. Things that were the norm 40 years ago may not be relevant today. I'm didn't say I recomended using springs made 45 years ago, new ones are available in marine parts stores and are stainless steel. I remember back in the day the springs would rust and corrode. |

The way I had it on my 1962 13 whaler was two springs and one of them had a cam lock (passenger side) to release the tension on the steering cable when you wanted to tilt the engine...Could it be that different boat places rigged them different? One/two springs? |

quote: Speaking of 70's lingo, the Seloc manual* for the one of the popular motors for early classic Whalers, has a passage where the author warns about a tempting technique that in reality is dangerous to the mechanic and ruinous to the part. He advises: "Such action would be a bad scene, a very bad scene". I just love it. Talk about a sense of another era. *Yeah, I know. It took me a while and work through the AOMCI to get hold of the factory manual. -Peter |

I'm still hoping for original pics that show detail...pad-eyes, links, etc. Sue from Twin-Cities sent a schematic. |

http://s1022.photobucket.com/albums/af349/tjxtreme/ Wire%20rope%20steering/ Here are a few pics of my setup, which is by no means perfect. I have it set up with the pulleys at the motor, because thats how it was when I got it. It is 2.5 wheel turns for the whole range of steering. It came with two springs, but I removed the port spring when I replaced the wire rope. The tension changes considerably depending on the tilt of the motor, so you will have to play around with it to find the right tension that will work for planing and tilted/shallow cruising. The connections between the pulleys are just whatever I had around, I don't think it really matters as long as it performs well and you INSPECT IT FREQUENTLY. |
| Binkster |
(The tension changes considerably depending on the tilt of the motor) That is becuase you are using the old spring with only 8 coils. Look at the coils in my photo (12 coils and stainless steel) big difference. Check my photo. Also you should be using 2 springs. You removed one spring becuase Tom unintentionally "steered"(pun intended) you wrong. with two larger springs you can tighten down at the tightest position and it will stay tight even when you change positions. Don`t sweat it though, your only using a 20hp motor. I don`t think Dick fisher wrote the "bible" on cable and pulley steering. Its been around alot longer than he has been. |
| johnnylaing |
Will I be ok without the "gear down" pulleys at the motor? I'm using a 25 hp...it sure would clean up the installation. |
| Binkster |
You could try it and see how it works. I believe without those pulleys you will need more cable, and that would be a pain to change and more expense, and maybe not work as well. I never tried it that way. Faster, harder steering may not be advantageous. |
| Binkster |
I meant to say if you terminate the cable at the motor hookup and it doesn't work out you will have to buy more cable to go back to original. |
| tjxtreme |
Binkie- can you suggest a source for the bigger springs? |
| johnnylaing |
I have the old cable that I can try it with before I commit to a length. Does anyone really know how it will handle/steer under power? It seems ok at rest. |
| tjxtreme |
"Does anyone really know how it will handle/steer under power?" What do you mean? Wire rope steering in general? Your specific setup? |
| Binkster |
I found the bigger springs at a marine parts store. |
| jimh |
Move to REPAIRS/MODS. |
| johnnylaing |
My specific configuration. Does anyone have a boat with 3 pulleys (none at the motor) as they were with a 1968 whaler 13? |
| Binkster |
You may have to pioneer that setup, I`ve never seen it. |
