swing keel stuck
Hi all
I seen there a while back someone had the problem of a swing keel stuck in the keel trunk. I have the same problem. and am now at a crossroads with it. I drilled a hole in the steel keel and used a 800kg ratchet winch onto an large anchor weight this pulled the keel down with some effort. I removed the keel winch and the keel pin. but still cant pull the keel out with the rust around where the pin was. I guess I need some thing to dissolve the rust that will not damage the gel coat. I have tightened up the ratchet pressure again and soaked the keel in diesel. And left it over night to see what will happen . Anybody got any better ideas on this. |

What size boat and what weight keel are you dealing with? And are you able to open the top of the trunk? Or flip the boat upside down? Or reach the pin location? (in other words, is the pin located up inside the trunk, of externally like a Catalina 22? Seems like you could clean the part of the keel that's out, then winch it back up, down, up, down, etc. to loosen the pin area a bit. Might help to flush it with a water hose while you're doing that. Then pull the pin again and go from there. -shrug- just a suggestion. It's hard to say without knowing the details. Rick |

Muratic acid should dissolve the rust and won't hurt the gel coat. In fact boatyards use it to clean hulls. Most auto supplies and paint stores have it. Be CAREFUL! I usualy put it, straight, into a spray bottle. It just takes a few seconds to remove crud and rust from the hull, deck, etc. Probably a little longer for your application. Note that it will instantly SMOKE when you spray it in. Only do this if you're sure you can rinse everything thoroughly with no proplem. Rick |

It got diluted by the water left in the block and didn't seem to do nearly as well. As an aside, it's used, diluted a pint to 3 gallons of water (I think) to clean the calcium deposits and stuff in a Lectra/San Type I MSD. I usually put it in a sprayer.

I've used it for years with no apparent problems. I've always been careful to make sure I do a good job of rinsing, just to be safe. Just went to the Star Brite site and checked out the MSDS, their barnacle and zebra mussel remover's active ingredient is hydrocloric acid. Not being someone that wants to play with hydrocloric acid, I think I'll buy their mix. Also checked out the sheet on thier rust stain remover, active ingredient oxalic. Being not afraid of oxalic acid, I buy wood bleach in the hardware and follow the instructions for disolving the crystals in warm water. Works great for grundgy harbor stains and the little jar of crystal makes gallons of cleaner for something like $7. Yeah, I'm cheap. or frugal rather. |

Ok guys The keel is down, sand blasted zinced and painted. I found it very hard to get Muratic acid here in Ireland stiff laws. So I used a sledge hammer with gentle taps and my 800kg ratchet winch and she came down with no damage to the boat thank god. thanks for all your help |

Wasn't me with the keel, Steve. It was Derry - he got the keel loose a
couple months ago. I've used Muratic acid safely for a bit over 40 years, for pretty much all of its uses. Rick On Mon, 10 Aug 2009 09:19:24 -0700, "Steve Lusardi" wrote: Rick. DO NOT USE this acid on the keel when it is installed on the boat. It is far too dangerous with your aluminum hull. This acid will dissolve aluminum while you watch and create terrific heat doing it. You have talked about this keel for a while now. My suggestion is to stop playing with it, blow it out of the hull and service/repair it as necessary. You get this wrong and you lose the boat.

Rick,
Sorry, you are correct. You have my apologies. I have used Muriatic acid successfully for many years, but that stuff is very dangerous if misused and it should never be used around aluminum.

pressure wash it/steam clean it,
Soak with PB-blaster, also soak with OLD,USED MOTOR OIL heat with heat gun... if this does not work repeat process... good luck |
