What is the primary risk if the tilt-lock is not properly engaged?

If the tilt-lock is not properly engaged, the primary risk is that the propeller may be damaged if it hits an object. The tilt-lock mechanism is designed to hold the engine in a specific position, particularly when the boat is moving through the water. If the tilt-lock is disengaged, the engine may move up or down unexpectedly, which can expose the propeller to shallow waters, debris, or other obstacles. If the propeller strikes something solid, it can lead to significant damage, including bending or breaking the blade, which could affect the boat's performance and safety.

The other risks related to overheating, capsizing, or fuel leakage are not directly associated with the tilt-lock mechanism. Overheating may occur due to mechanical failure unrelated to the tilt-lock, while capsizing is typically linked to stability issues rather than engine position. Fuel leakage could result from various boat malfunctions but is also not a direct consequence of the tilt-lock's engagement status. Understanding the role of the tilt-lock in protecting the propeller emphasizes the importance of ensuring it is correctly engaged for safe boating practices.
