Jerry, look under the bridge deck. You will see an aluminum tube that runs down and then aft into the bottom of the keel. You'll have to take the board out from behind the companionway step to see it all the way back.
As for underneath, up in the CB slot in the keel, well, I haven't had to look up in there yet. I do remember Joe "Trinkka" Alves saying there should be a sheave up inside on the 222, that his was missing at the factory, and after chafing through several pendants, he replaced it. The 192 being the smaller boat designed after the 222, it will be similar, but possibly not exactly the same.
