See if we can arrange something when you get back!
The engine in the Sea Doo that the Qrv is based around is the Rotax 4 stroke with closed loop cooling system, I have no reason to believe that it would not be good for the same 3000 Hours you quote for the 200 outboard. I would also add that this is the same engine that Sea Doo fit in their £56,000 Sea Doo Challenger 23ft boat, so I would say that BRP see this as quality product.
As to what make our design different, to be honest I wasn't aware of any similar product and certainly nothing built to withstand the forces that can be put on a craft designed to go 70mph and using the s3 Hull shape.
