How is speed controlled on a personal watercraft?

• A. Controlled with finger or thumb control on handlebar
• B. Controlled by wind speed
• C. Controlled by water depth
• D. Controlled by engine temperature

Answer: (A)

Speed on a personal watercraft is controlled by the throttle on the handlebar—the twist grip or thumb throttle that varies engine RPM. When you twist the throttle, more fuel reaches the engine, RPM rises, and thrust increases, making you go faster. Releasing the throttle lowers RPM and slows you down. Wind speed and water depth don’t set the engine speed; they affect handling and maneuvering but not how fast you’re actually asking the engine to run. Engine temperature can cause the system to reduce power if overheating, but that’s a protective response, not the way you control speed. The operator’s control of the throttle is the primary mechanism for adjusting speed.
