    Kawasaki use to state pump thurst in lbs in their specs. Maybe could start there and figure something out. Beats me how they came up with the number though.

    so a 2 stroke 2011 Kawasaki Jet Ski 800 SX-R is rated at 700 lb of thrust. but I don't know the hp rating but its a start.

    2012 Kawasaki Jet Ski Ultra 300X 300 hp, 1,769 lbs thrust.

    nozzle size will also affect thrust as the smaller the reducer the greater the thrust. Think you would have to measure (how I do not know) then apply some sort of formula. Seams like a lot of factors will affect it. Good luck. Let us know what if anything you figure out.
