===Final record attempt===
To increase publicity for his rocket car venture, in the spring of 1966, Campbell decided to try once more for a water speed record. This time the target was {{Convert|300|mph|km/h|abbr=on}}. ''[[Bluebird K7]]'' was fitted with a lighter and more powerful [[Bristol Orpheus]] engine, taken from a [[Folland Gnat]] jet aircraft, which developed {{Convert|4500|lb-f}} of thrust. The modified boat was taken back to Coniston in the first week of November 1966. The trials did not go well. The weather was very poor, and ''K7'' suffered an engine failure when her air intakes collapsed and debris was drawn into the engine. By the middle of December, some high-speed runs were made, in excess of {{Convert|250|mph|km/h|abbr=on}} but still well below Campbell's existing record. Problems with ''Bluebird''{{'}}s fuel system meant that the engine could not reach full speed, and so would not develop maximum power. Eventually, by the end of December, after further modifications to her fuel system, and the replacement of a fuel pump, the fuel starvation problem was fixed, and Campbell awaited better weather to mount an attempt.{{citation needed|date=May 2024}}
