The outboard motor catalytic converter includes exhaust pipes that are connected to exhaust manifolds of an engine of the outboard motor. Catalysts are installed inside the exhaust pipes, and at least a portion of each of the exhaust pipes, which corresponds to a place where the catalysts are installed, is formed to have a double structure constituted of an inner pipe and an outer pipe.
