It is a direct replacement for Mercury Marine part number 60930, letting boat owners restore proper exhaust water shutter function without sourcing a full Mercury Marine assembly. The shutter is finished in white and measures 0.25 inches thick, matching the dimensions of the original component it replaces. Each unit is sold individually and is built to the fit and function of the OEM part it is designed to replace.\u003c\/p\u003e\u003cp\u003eThis shutter is a straightforward maintenance-and-repair item for owners servicing the exhaust water system on applicable Mercury Marine-equipped boats.
