Sierra Molded Hose 18-2774, Replaces 875847, for Volvo Penta AQ290, AQ290DP

The Sierra 18-2774 is a molded cooling system hose engineered as a direct replacement for the OEM part on Volvo Penta AQ290 and AQ290DP sterndrive engines. Unlike straight-cut hose sold by the foot, this hose is molded to the exact bends and contours required by the original cooling system routing, so it seats correctly without kinking or restricting coolant flow. It is built to handle the heat, pressure, and constant exposure to raw water or coolant found in a marine engine bay, making it a durable option for restoring proper cooling system integrity.

Each 18-2774 hose ships complete with two 18-7306 clamps, so the kit includes everything needed to remove the old, cracked, or collapsed hose and install the new one without sourcing separate hardware. This makes it a straightforward replacement for engine owners performing routine cooling system maintenance or repairing a failed hose before it leads to overheating or coolant loss.
