It connects to the bottom of the trim cylinder and measures approximately 11 1\/4 inches in length, matching the trim cylinder casting numbers 98704 and 98704-1. Built from metal with a white finish, this hose is engineered as a direct replacement for the original equipment hose on applicable MerCruiser sterndrive setups, fitting R, MR, Alpha One, and Bravo I, II, III, X, XR, and XZ drive configurations. Because the power trim system uses separate port and starboard hoses that route to opposite sides of the trim cylinder, installing the correct side matters -- this listing is the starboard hose only; the port-side counterpart is a different Sierra part number. The hose is intended as a like-for-like replacement for the OEM Mercury Marine hose bearing part numbers 32-99902 and 32-864589, restoring proper hydraulic fluid flow to the trim cylinder circuit. Replacing a cracked, corroded, or leaking power trim hose helps prevent hydraulic fluid loss, restores trim\/tilt responsiveness, and avoids further strain on the trim pump or cylinder. At 0.12 pounds, it is a compact, lightweight component that a marine technician or experienced boat owner can install without major disassembly beyond accessing the trim cylinder fittings.\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 18-2136\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide:\u003c\/strong\u003e Starboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Length:\u003c\/strong\u003e 11 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal Tube Length:\u003c\/strong\u003e Approximately 11 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 11.25 inches L x 11.25 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999237200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e R, MR, Alpha One, Bravo I, II, III, X, XR, XZ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Cylinder Casting Number:\u003c\/strong\u003e 98704, 98704-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 32-99902, 32-864589\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits MerCruiser MCM 120-260 engines with R, MR, Alpha One, and Bravo I, II, III, X, XR, and XZ stern drives.
