Had a great run with the new boat from Pensacola to her new home in Pass Christian. Stopped over at Dauphin island had a great meal at the seafood restaurant / bar and they let me tie up for the night. Checking the engines the next morning, I discovered a shaft bolt in the bilge and the remaining shaft bolt with a bit of broken seizing wire still attached. The bolt threads were too far gone to be re attached so all I could do was tighten the remaking bolt and double seize wire that one. The delivery captain told me he had some vibration in the engine on the way from Punta Gorda to Pensacola. Now I know why. I have never heard of a bolt that was wired coming unbolted.
