Greetings to all.

I am new and need advice please on building powerful jet boat that will run through large rapids. It must have one jet drive with very high thrust output and power RC moto boat. I need tremendous thrust out of a small jet drive - I need it to run a jet boat with heavy cameras through large rapids! I am also unsure of best type of jet props that will run in the jet drive. Any help and support would be most welcome. I am also welcome of the shelf products that meet this demand but can prototype if need be.
