Morale, Welfare, and Recreation (MWR) Boater Safety Practice Exam

What should be done with the motor when in approximately three feet of water?

1. Leave it running

2. Raise it to avoid hitting the bottom

3. Turn it off immediately

4. Put it in full throttle

The correct answer is: Raise it to avoid hitting the bottom

When navigating in shallow water, specifically in approximately three feet of water, raising the motor is the safest and most prudent action. This practice helps to avoid potential collisions with underwater obstacles, such as rocks, logs, or the bottom itself, which could damage the motor or cause the boat to become immobile. Keeping the motor raised allows for better maneuverability and reduces the risk of the propeller striking the bottom. This is particularly important because operating in shallow water can lead to a variety of hazards, including getting stuck or causing harm to the marine environment. In contrast, leaving the motor running could lead to damage to the propeller and lower unit if it strikes the bottom. Turning it off immediately may not allow for adequate control of the boat, particularly if there are other vessels nearby. Putting it in full throttle can increase the risk of running aground or colliding with submerged objects, which can cause serious damage to the boat and pose safety hazards to passengers. Therefore, the most prudent choice in shallow water is to raise the motor to ensure safe navigation.
