Hey, thanks for the quick response, I was only asking as I grounded last year and am worried about impact maybe having loosened the bolts/nuts slightly and if a retorque was a good idea. I have owned the boat since last June, bought and picked up in T.O.I doubt that you would have to re-torque but if you want to check I have attached a standard torque reference chart. How long have you had the 326? Did you get it from Port Credit? I had a buddy with an 04 326. Have not seen many, just wondering if it was the same one.
Clean threads, yes. Lubricated threads, no. Standard torque charts are for clean and dry threads. Lubrication lowers the friction coefficient between the threads and will increase the resulting torque.consider that most torque charts are for clean and lubricated threads
Was it a soft grounding or hard, i.e. mud or rock, and was it full stop or slow motion. The keel to hull joint is fairly strong and unlikely the keel bolts would be affected. I would be concerned about damage to the hull fore and aft of the keel. It will flex in a hard grounding and separate the layers. It might be a good idea to have a surveyor have a look at the hull itself and the keel joint.Hey, thanks for the quick response, I was only asking as I grounded last year and am worried about impact maybe having loosened the bolts/nuts slightly and if a retorque was a good idea.

Do you have a source for this information ?Damage to the female threads in the keel,
I think you'll find as many theories about re-torqueing keel bolts as there are different keels.and have always wondered about re-torqueing keel bolts.
