sometimes proper lubrication can quiet those troublesome fellow sailers. Try dispensing approx 12 ounce per hour to the squeekiest. Avoid direct application to the hardened nut that holds tiller. Sometimes you will find a TFS that was designed from the start with no nuts at all, use caution! I had one of these and tried to remove some threads from it on the deck. It seems I was working too fast and caused irrepairable damage. Finally by taking my time and applying a little heat I was able to remove enough threads to get by. Also watch closely for color change in all recently installed TFS. TFS are available in all natural colors and usually have strong color retention. Some TFS will slowly turn yellow when you least expect it during a rough sea. This is almost always followed by a change to green and an increase in noise of the internal machinery of TFS.STAND BACK during debris removal! Green tint will now slowly become red for rest of day.
