The u-joint transmits rotational drive from the driveshaft to the propeller shaft through the drive's u-joint bellows\/gimbal assembly, and it is a wear item that should be inspected and replaced as part of routine sterndrive maintenance or whenever play, corrosion, or roughness is found in the joint. Permalube construction means the joint is factory-packed with grease at the needle bearings, so it does not require an external grease fitting to be serviced during installation. The part is machined for a precise fit against the yoke and cross bearing surfaces it mates to. Sierra manufactures the 18-2097 as a cross-reference to the original Mercury Marine u-joint, so it installs the same as the factory part on the drives listed above without modification.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-2097\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e U-Joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLubrication:\u003c\/strong\u003e Permalube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Bravo One, Two, \u0026amp;
