Which of the following is recommended as part of the annual maintenance program for a gasoline-powered boat?

Examining thru-hull fittings for signs of leakage or corrosion is a crucial part of the annual maintenance program for gasoline-powered boats. Thru-hull fittings are essential components that allow water to enter and exit the boat's hull, and their integrity is vital for safety and performance. Any signs of corrosion or leakage could lead to water ingress, which poses a serious risk of sinking or damaging internal systems. Regular inspection helps identify and address potential issues before they escalate into more significant problems.

Maintaining these fittings ensures that the boat remains seaworthy and prevents costly repairs in the future. Keeping a close eye on all critical systems, including those that manage water flow, is essential for responsible boat ownership and safe navigation.
