Thanks Cwatters, Using the speed of the boat and the tension of the rope, what is the formula to calculate the power(thrust) required to reach a certain accel. / top speed?

Thanks billy_joule, I have seen wavejets what's the acceleration or top speed like? I'm looking forward to power it with a fuel engine to have more power but runtime of at least 30mins would be fine if it were powered by LI ion batteries.

Yes true! It is supposed to be very light not more than 10 - 15kg that's why i averaged assumption of total mass at 100kg.

Hi everyone! As an experiment I am trying to calculate building my own PWC similar to a jetski assuming it is for sea level use. I really appreciate all detailed answers as I want to understand. The impeller will be installed under rear of craft, engine is mounted on top. Given Information...

Thank you Berkeman! Will check it out now :)!

Hello ! I'm a new member here and want to learn about fluid dynamics/ mechanics for several hobby interests specifically to do with impellers and flow rates. Look forward to becoming part of the community! :):)
