fparry These sound like the same bolts I am attempting to replace on my Shock Santana. The originals are galvanized steel, 1" diameter x 2.5" length with a tapered head (counter sunk into the keel)

Schock currently uses stainless steel bolts of the same configuration on their new boats. I ordered a complete set of the SS bolts, washers, and nuts. They have not arrived yet but you might want to contact them as they sold me the last ones they had but apparently were getting more from their supplier. They were very inexpensive.

Eleuthera1 Thanks for the info, much appreciated.

RXBOT As bronze bolts run around a minimum of 70,000 PSI tensile stregnh per square inch I would not be too concerned. There are better options but bronze is relatively easy to find. Up to the poster to decide what is best route to take.

Jeff_H You might consider using replacing the bolts with monel, which may be cheaper and easier and be a far superior metal than trying to get a machine shop in the States to produce the bolts and galvanize them. Also New Zealand and Australia may be closer and cheaper as well.

Eleuthera1 I live in Tahiti and we have some good machine shops but no galvanizing facilities, so looks like a State side project.Do you have an email address for Pungo machine company?

keel bolts

Thanks for the info, plans are in German but only give diameter, I will have to remove to get the exact length, She has a cast iron keel so I will be sticking with Galvanized bolts

sailingdog One issue with going with bronze, it is weaker and more fatigue prone than steel IIRC.

sailingdog Where are you located? If you're in Tahiti, the suggestions I have won't do you much good. One machine shop that I'd highly recommend is the Pungo Machine Company in Pungo, NC. They were very helpful when I had to re-build a sail drive leg on a recent delivery trip.
