Where are freeze plugs on a mercury 350 v8 boat engine?
Freeze plugs, also known as core plugs or expansion plugs, on a Mercury 350 V8 boat engine are typically located on the sides of the engine block. They can also be found on the cylinder heads, depending on the specific engine design. Their primary function is to protect the engine from damage due to freezing by allowing coolant to escape if it expands when frozen. To locate them, check the sides of the engine block and the rear of the cylinder heads for small, circular metal plugs.
