Who invented the Jet Ski?

Answer 1

The Jet Ski was invented by Mr John George Ian Erier Cruikshank my old tutor.

date unsure but I do have the precastings for the propulsion unit that Kawasaki did not see a need for at that time.

The semi helical thruster (Cruiky's) major invention has amazing propulsion power.

The Jet ski was originaly intended as a vehicle to house the propulsion unit.

The conception of the semi helical thruster, and the jet ski were from

Erier Lab Mordialoc Melbourne Australia.

Kawasaki later replaced the prop on the jet ski , but not with his truster.

He was always troubled about this, as by his calculations his truster was Superior in energy transfer than the jet unit and more fuel efficent.

The pricipals behind Cruiky's breakthrough in propultion systems was unlocked by another Lab some 5 years later ,and where it is used to propell container ships reduces their fuel usage by somewhere in the area of 30% .

Cruiky originaly came to Australia as the British Nuclear Industry advisor to Australia
