Re: [Amel Yacht Owners] Windlass bolt to deck
toggle quoted messageShow quoted text
I have had great success over the years removing stuck and broken bolts in this manner:
I use a clay like substance called here in the USA Duct Seal.
I build up a small dam around the offending bolts and fill the dam with PB blaster for a week. The bolts almost always are loose by that time if not I continue the process eventually they come out.
It is also important to try to turn the bolt in both directions to spread the PB blaster.
When I re install them I use a paste called never seize high temperature. It is especially good on the outhaul shaft.
Works like a charm.

Danny's thru-bolt solution sounds good and the drilling, as he points out, will be the key to success. With the good amount of bolt you've got left above deck you may want to try removing it before you go to drilling it out, even though it may shear off. After a good soaking with penetrants (use some acid too, to attack the salts) you may be able to lock two nuts on top to screw it out. If or when that fails you could weld a short bolt of the same diameter to the broken end and use the new bolts hex head to turn. The welding heat may also help break the threads free. If still no joy,you're likely into drilling it out,. Here's a great link to using tread inserts after drilling out the bolt. https://racemagazine.com.au/cars/thread-repair-how-to-fix-broken-bolts-and-stripped-threads
Good luck with it,

Hi mike. I drilled mine out and put a bolt through. I now have a nut top and bottom
