Tighten the screw until it is seated, then turn it an additional 45 degrees, or use a torque wrench to tighten to 7 ± 1 Nm (5.2 ± 0.7 lb-ft). Failure to lubricate the gasket and threads can cause damage and lead to leaks.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my lower unit drain plug gasket?\u003c\/strong\u003e\u003cbr\u003e\nA: It is recommended to replace the drain plug gasket every time you change your lower unit gear oil.
