Sierra Power Trim Hose 18-2108, Replaces Mercury Marine 32-59841, Fits MC-I Drives with V-8 Engines

The Sierra 18-2108 Power Trim Hose is a 46 inch replacement hose built for the power trim system on Mercruiser MC-I drives paired with V-8 engines. It connects the trim pump to the drive unit, carrying hydraulic fluid that raises and lowers the outdrive under power. The hose measures 46 inches in length with a 0.13 inch width and uses a 1/8 inch fitting size, matching the original hose routing and connection points on these drives.

Finished in white, the hose is sized to be a direct fit for the MC-I drive and V-8 engine combination it is designed for, and it corresponds to Mercury Marine part number 32-59841. Replacing a cracked, soft, or leaking power trim hose restores proper hydraulic pressure to the trim system, preventing slow or failed trim response and fluid loss around the pump and drive fittings. Each unit ships as a single hose ready to install in place of the original equipment line.
