I can make you feel better. Every year my family would go to Trinity Lake in N. Cal to water ski for 10 days from his house in Oregon City. My dad had a flat-bottom jet that he rebuilt the top end of the motor and didn't finish assembly before we left. He finished at the Lake. Then he started the motor, drove out at about 100 yards from shore something started sounding bad. By the time he got back to shore the motor wouldn't turn over. In his rush to leave he forgot to tighten one of the rocker Ts on the 472 Cadillac motor. Those motors, the oil goes up through the cam galley then down to the mains. The T on the Cylinder number 1 was the one which loosened. It lunched the entire motor.... so we had towed that anchor from Portland to California and back.... never used it.
