Only a slight reduction in RPM will provide a match where the engine makes more power than the jet can absorb. Hence, no engine overloads. Jets Don't Protrude Below the Hull- No underwater appendages cut running gear damage to a minimum for greatly reduced damage loss and more time on the job collecting a paycheck.
Shallow draft opens up new fishing areas, travel routes, shortcuts.
The ability to navigate under lower tide conditions can increase working time. Lack of appendages provides better safety for personnel plus reduces damage to nets, lines, etc. Lack of propeller and shaft vibration prolongs mechanical and electronic life plus provides more pleasant crew and passenger environment. Simple Construction- Simple jet construction saves on repair costs.
