After witnessing the success of Banks marine engines in racing, Lou Brunette brought his triple outboard Jones Tunnel boat to Banks for an inboard/stern drive conversion based on the famed engines. Banks developed and rigged the potent 398-cubic-inch engine and drive system at his San Gabriel facility. An innovative tunnel and stern drive control designed at Banks optimized top speed as well as high-speed maneuverability. The result: the newly equipped boat was able to reach speeds in excess of 140 miles-per-hour. The new configuration not only proved extremely powerful and stable but went on to win the Parker 9-Hour Enduro and was the APBA Endurance Tunnel National Champion for the next five years running.
