Volvo Penta's official maintenance-parts catalog specifically identifies this part as the exhaust bellows kit for these drive families — separate from the drive-joint (U-joint) bellows used in the same assemblies. Getting the right bellows by part number and drive family avoids a common swap mistake: the exhaust bellows and the U-joint bellows sit close together on the drive but serve different sealing functions.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cp\u003eConfirmed by Volvo Penta official maintenance-parts catalog:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSX Sterndrive\u003c\/li\u003e\n\u003cli\u003eDP-S Sterndrive\u003c\/li\u003e\n\u003cli\u003eDP-SM Sterndrive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eExtended application references (verify by serial number):\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSX-S\u003c\/li\u003e\n\u003cli\u003eSX-C \/ SX-C1 \/ SX-C2\u003c\/li\u003e\n\u003cli\u003eSX-R \/ SX-R1 \/ SX-R2\u003c\/li\u003e\n\u003cli\u003eSX-M \/ SX-M1\u003c\/li\u003e\n\u003cli\u003eDP-SM variants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cblockquote\u003e\n\u003cstrong\u003eFitment Notice:\u003c\/strong\u003e Always confirm by exact sterndrive model \u003cem\u003eand\u003c\/em\u003e serial number before ordering.
