Editing Jetboat (section)

==Drawbacks==
The fuel efficiency and performance of a jetboat can be affected by anything that disrupts the smooth flow of water through the jet unit. For example, a plastic bag sucked onto the jet unit's intake grill can have quite an adverse effect.

Another disadvantage of jetboats appears to be that they are more sensitive to engine/jet unit mismatch, compared with the problem of engine/propeller mismatch in propeller-driven craft.{{citation needed|date=April 2014}} If the jet-propulsion unit is not well-matched to the engine performance, excessive fuel consumption and poor performance can result.
