Sierra 18-2115 Power Trim Hose, Port Side, Replaces 32-99903-1 & 32-864959, Fits MerCruiser MCM 120-260 & BRAVO

The Sierra 18-2115 is a port-side power trim hose that connects to the bottom of the trim cylinder on applicable MerCruiser stern drive setups. It is built with a metal tube and hose assembly finished in white, designed to carry hydraulic fluid to the trim cylinder as part of the power trim system. The metal tube measures 11 1/2 inches with a 14 inch hose length and a 1/8 inch fitting size, matching the original equipment dimensions for the trim cylinder casting it serves (Casting #14035-1).

This hose is engineered as a direct fit replacement for the original MerCruiser trim cylinder hose, matching OEM specifications so it installs without modification. It is intended for MerCruiser MCM 120-260 and BRAVO applications, and is also referenced for R, MR, Alpha One and Gen II drive fitments. Because this is the port-side hose, it is not interchangeable with the starboard-side hose (a separate part number); confirm you are ordering the correct side before installation.
