They're junk. I have experience with a few of them. The worst was a 14' Nautica RIB jet. It smoked like crazy, was so loud at hull speed you needed ear muffs, and problematic. The 4 stroke outboards have come so far that the jets don't even come close.
The jets use a lot more fuel. Need a lot more maintanence. They are a lot louder inside of the boat because the motor is generally mounted under the console. They don't have the performance of an outboard. You really cannot go in any shallower water then a 4 stroke one. If they have a waverunner motor they vibrate and smoke. Steerage at slow speeds with them is horrible. The best thing about the jet's is if you have to jump overboard fully dressed to clear a plastic bag out of the intake with guests on board. IMO they have no advantages.
