Sierra 18-2758 Exhaust Bellows, White, Fits Volvo AQ200 250 270 275 280 280DP 290 290DP, Replaces Volvo Penta 875848 876631

The Sierra 18-2758 is a white exhaust bellows built for Volvo AQ200, 250, 270, 275, 280, 280DP, 290, and 290DP engines. The exhaust bellows connects the exhaust system to the outdrive, flexing with engine movement and steering while sealing exhaust gas and cooling water so they exit the drive without leaking into the bilge or engine compartment. Because the bellows works under constant heat, vibration, and saltwater or freshwater exposure, replacing a cracked or hardened bellows before it fails helps prevent water intrusion and exhaust leaks around the transom assembly.

Each 18-2758 kit includes one bellows and two Sierra 18-710-52-2 hose clamps sized 2-13/16 inches to 3-3/4 inches, so the clamps needed to complete the installation are included in the box rather than sold separately. The bellows is built to meet or exceed the specification of the original equipment part it replaces, and it interchanges directly with the Volvo Penta, Mallory, and GLM part numbers listed below for the same application.
