How do you locate the nut to drain oil on a 60 hp 4 stroke mercury outboard?

To locate the oil drain nut on a 60 hp 4-stroke Mercury outboard, start by tilting the engine up to a comfortable angle. The oil drain nut is typically located at the bottom of the lower unit, near the propeller shaft. It is often a hexagonal or square-shaped bolt. Make sure to have an oil pan ready to catch the old oil when you remove the nut.
