What is the primary purpose of a boat's trim in relation to fuel efficiency?
Answer: To reduce hull drag and improve planing
Proper trim keeps the hull at an efficient angle, reducing drag and improving fuel economy.
You notice the engine temperature gauge climbing rapidly. What is the most likely cause?
Answer: A blocked raw-water intake or cooling system
Overheating is commonly caused by a blocked cooling water intake restricting engine cooling flow.
What should you check to prevent carbon monoxide poisoning aboard a powerboat?
Answer: Exhaust system for leaks and proper ventilation
Leaking exhaust and poor ventilation allow deadly carbon monoxide to accumulate in cabins and cockpits.
When docking in a strong crosswind, the best technique is to:
Answer: Approach at a steeper angle and use short bursts of power
A steeper approach angle and controlled power bursts counteract the wind pushing the boat off course.
What is the recommended way to store a fire extinguisher on a boat?
Answer: Mounted in an accessible location away from the engine
