My foot control trolling motors have little plastic/nylon pulleys in them
The steering cables come out of the foot pedal over these pulleys. On one of my controls that is several years old the axle holes in the pulleys have worn and they wobble on the shaft. This causes steering cables to pop off. I was wondering how well 5052 aluminum (I have some laying around) would work as replacements. Would it wear slower than the plastic, but still be enough softer than the cables and the axles to not cause damage? |

Generally parts for boats are anodized but making a few spare pulleys will probably "solve" any corrosion problems. By the way, do not mix aluminum and stainless in salt water environments unless you insulate them from each other. Cheers, Bruce |

Both are very low copper. the 60xx is harder. Most of the river jetboats are 5052, with some of the bottoms having 6000 series in critical contact areas. but I would just bore the pulleys and add a bearing hub. A new Delran, or a roller bearing, or a bronze bushing. |

Yup, or just make some brass pulleys. They're small. |

Yup, or just make some brass pulleys. They're small. I knew an old boat builder and lobster fisherman in Maine that used flat chain as steering "cables". He had a few of the small iron pulleys that you use on porch awnings to guide it. I asked him why not proper plastic coated cables and good pulleys and he told me that the chain and cast iron pulleys were cheaper and he just replaced them every couple of years. Said it was a lot cheaper then the fancy plastic coated cable and bronze blocks. Cheers, Bruce |

For small outboards single control cable rack and pinion steering, for medium size dual cable, and for big ones go hydraulic. If lubed properly the direct cable steering willl last the life of the boat. NOT pulley cable with spring block like the mentioned party was using for his chain. Still cheap is cheap. |

Cheers, Bruce I was replying to the guy who stated Marine Aluminum Alloy was 6000 series. 5052 is very much a marine alloy. My 1991 Aluminum river jetboat is made of the stuff and still is in fine shape. Only corrosion hole in the bottom (3/16 thick) was in the anchor locker where a copper wire had fallen into the muck that forms around the limber hole. |

Custom aluminum working boats made in this part of the country usually are made of 5052 for the hull, with 6061 used for ribs and joining angles, etc. -- Ed Huntress |

Lots of older boats used a clothesline style pulley system to between the steering motor and the big motor. It was basically a pull/pull system around the boat under the gunnels with one or two spring loaded pulleys to maintain tension. Then there was a take up drum on the back of the steering wheel. |

One of the things I was also considering with the aluminum ones is to cut the cable grooves deeper. |
