propulsion team dissects a jet ski

Fueled by their desire to propel the sub with a jet of water, the propulsion team hit on the idea of dissecting a jet ski.  Our fiberglass mentor, Mr. Whitley, conveniently knew of a used one available for this purpose.  (Thank you, Mr. W!)  Mr. Riz picked it up, and the propulsion team set to work.  Below are photos of the team taking the jet ski apart in their quest to understand how it worked.   Some of the lessons learned are:  it's harder than you think to take apart a jet ski; a jet ski propulsion system is likely considered a prop design because it has radiating blades (we're hoping to enter the non-propeller category); it might be difficult for a human-powered vehicle to supply the rpm necessary for this system to work well.
