When assessing whether a vessel is experiencing engine trouble, one of the most telling signs is unusual noises coming from the engine or an increase in engine temperature. These symptoms indicate potential mechanical issues, such as overheating or internal damage, which can compromise the vessel's performance and safety.

Unusual noises might include knocking, grinding, or a lack of the normal operational hum, suggesting that components within the engine may be malfunctioning. Similarly, an increasing engine temperature could signify that the cooling system is failing, leading to overheating, which can cause severe damage if not addressed promptly.

In contrast, a vessel moving faster than usual typically implies that the engine is performing optimally, rather than struggling. A full fuel gauge indicates adequate fuel supply rather than engine health, and a calm area does not provide any direct insights into the functionality of the engine. Focusing on the signs that suggest mechanical failure will ensure effective troubleshooting and maintenance for the vessel.
