Mercruiser New OEM Fuel Cooler to Transmission Oil Water Hose Line 32-808045

Brand new, genuine Mercury Mercruiser New OEM Fuel Cooler to Transmission Oil Water Hose Line 32-808045. This is a factory original equipment item, not aftermarket.

This is a genuine Mercury Marine factory‑molded coolant hose designed to channel seawater between the fuel cooler and transmission or power‑steering oil cooler. Precision molded from marine-grade rubber, it maintains a reliable seal and internal routing designed to match Mercury’s closed‑cooling schematic—free of kinks or twists. Built to withstand engine vibration, hot coolant, and saltwater spray, this hose ensures efficient heat exchange and helps protect sensitive components like the fuel cooler and oil cooler from overheating. As an OEM part, it ensures perfect fit and durability on V‑6 and V‑8 fuel‑cooled Mercruiser sterndrives and inboards (e.g., MCM/MIE 305, 350, 377, 454, 502 engines).

• Factory-molded OEM hose—ensures correct routing and dimensions
• Internal diameter: 1¼″ (32 mm)
• Special‑order item; molded per spec to prevent leaks and coolant flow restriction
