marine engine
Watercraft propulsion unit
A marine engine is an engine designed to power watercraft—boats, ships, and other vessels.
Marine engines must withstand constant exposure to water, salt, and humidity, so they differ from automotive engines in their cooling systems, corrosion resistance, and construction.
They range from small outboard motors to massive diesel engines in cargo ships.
