Wankle (rotary) engine in a jet boat?
Would putting a Wankle (rotary) engine into a jet boat be a good idea? would it be hard to do and would it work well? Thanks
Wouldnt it be far lighter and have just as much if not more power as say the Ford Bronco V8 engine i have in my Hamilton jet boat. Ive heard that they have had rotary engines up to 40000 rpm? that would be far more powerfull than a piston engine.

Vehicle engines do not spin at 40,000 rpm. It may spin up to 12k RPM when pushed, but not 40k. The Rotary engines got terrible fuel MPG in the RX7, what makes you think it would be better in a boat. Jet boats have terribly poor fuel usage, it'll be even worse with a Rotary and much slower with the small amounts of "Torque" they produce. Stay with the "Piston" engine. You can do much more for power with a piston engine.

It sounds like it could be a good idea, the wankel has a lot going for it. It needs a jet unit that is optimized for higher rpm and those are used on things like Yamaha jetboats. Those engines rev high, not 40000 rpm but maybe 10-12k rpm would be ok for the jet unit.. You would have to marinize the engine but I think it could be done. Not saying it should be!

i don't think it's going to be a good idea. mainly because it lacks torque.
- and, i can just think of other problems like
- it's going to be extremely loud , louder than a piston engine, unless you're going to run a huge muffler, it might even shoot flames, .....

I wouldn't because they don't produce much torque and burn oil like its going out of style.
