There are examples of small ski boat designs that were built with smaller jet-skit engines, mostly these are outboard designs that are modified to accept a jet drive. Our idea is to design a larger boat that is designed from the beginning to be powered by a large PWC engine and pump.
Advantages over adapting existing designs : 1) running surface will be designed for jet-drives, which have differences from running surfaces designed for outboards. 2) The transom area can be made much more aesthetically pleasing, can incorporate reverse and curved transom and even swim platform. Seating, center of gravity, etc. all planned with Jet-drive in mind
We picked up a donor jet-skit to use on the prototype. The runabout will be deigned to accept not just this brand, there are several others made by other companies that will work just as well. Its a Kawasaki 1500 cc, 3 seater, 4 cylinder, 4 stroke motor, rated at 150 hp, 35 hours on it.
The idea is to use almost everything from the PWC; motor/pump, all the rigging, steering helm (will give it a wheel) , gauges, fuel tank.
here is the donor....
This will be a fun one to watch.
