What this video covers
A late 1970s or early 1980s Mercury 7.5hp long-shaft outboard requires a carburetor rebuild kit, new spark plugs, fresh gear oil, and a new impeller to restore performance.7:31 The rebuild process involves removing the choke cable assembly, disconnecting the fuel line, and disassembling the carburetor bowl to clean the float, needle valve, and internal jets.9:38 The fuel pump diaphragm, located between the carburetor plates, must be reassembled carefully to ensure an airtight seal, as air leaks defeat the carburetor's fuel-metering function.23:18 Replacing the fuel line clamp with a standard hose clamp is recommended for low-pressure lines.10:22 Additionally, the boat's navigation lights are replaced with LED units to reduce current draw, and rust on the hull is addressed via wet sanding.4:39
